Dr. Art: Do you think you could change the parameters so that you could hack the ECM and disable UT's Jeep whenever you want? That would make him behave!😆
Just because the timing table stops at 4900 doesn’t mean the computer will go haywire after that. It just means it will continue on with the same amount of timing as was in the highest table, so no need to go crazy trying to get a different timing table. Also you might as well leave the closed loop parameters alone, since WOT will never be closed loop, so it will have no effect on dragstrip times, but forcing it into open loop all the time will negatively affect drivability and fuel mileage under normal driving conditions. Realistically, the only time you would want to change that would be if you went to a colder thermostat, so say if it originally had a 195 thermostat, it might command closed loop at 170 or 180 degrees, but if you put a 180 thermostat in there to keep it cooler, it will constantly be going in and out of closed loop, so you could drop that temp down to 160, and then it wouldn’t be switching to open loop every time the thermostat opens.
@@michaellehmann2803 I agree with your comments, just stating what the use would be. Seems like you'd be always questioning the computer when something like fuel trims changed, or something was wrong. A bigger discussion about how the computer operates under load in either open or closed loop. My 98 F-150 idles great, stone cold, as the computer intervenes, it develops a miss at idle. 🤔?
Just a little while back I asked UTG how he was going to tune this Jeep without a separate aftermarket flash tuner. He said to watch your channel to find out. Thanks for posting this. Very interesting. I’ve only got experience with the flash tuner units. Mostly for Harleys like the Dynojet Power Vision or Screaming Eagle Race Tuner.
Pretty cool. I've been looking for a decent XJ to build into a V8 hot rod, but it seems that a lot of people have recently beat me to it. Bummer, but cool. 👍🏼👍🏼
I need to learn HP tuners and burn chips for my 94 Chevy TBI truck. One day! I want to increase my timing across the board... because I aways set the dizzy at like 2 degrees advanced it scoots better than zero It think I obtained all the definition files. I play on my LT1 some times... 93-95 OBD1 LT1 chevy's are the easiest to get into tuning. So cheap
Check out dynamic efi, bobr makes a whole computer for tbi's that you can tune with a USB straight to your laptop and it can auto tune too if you aren't savvy like me lol, it's been working good so far, I have a 1990 and I'm planning on going with vortec heads soon
really interested to see how you will tune this engine (ecu) to gain 40hp like tony stated in his other video with no real mechanical performance mods (keeping it stock). you can adjust WOT fueling and of course raise the ign table to run high octane fuel. but in my opinion there wont be more than 10-15hp max to gain on an otherwise stock engine. also, i see that each flash is 49 usd, so this can get quite costly. for proper fueling, imo you will need a wide band lambda setup to really nail afr lambda between approx. 0.87 and 0.92 for best power. otherwise you will be stabbing in the dark and wasting alot of costly flash credits. im curious to see the results!
I had a coworker that put a n/a 2jz in a 99 Dakota and did a china turbo kit and cheap tune and that thing moved like kinda stupid fast for what it was
Do you have to purchase a credit every time you tune it? Or does 1 credit work for the life of each vehicle? I have a 99 cherokee and am looking into hp tuners to tune it. Any information would be helpful. Thanks

@@DrArtshotrodrehab Thanks Art! Did you just happen to have one laying around or did you find a source? HP Tuners discontinued them to the best of my knowledge awhile back (my son was looking at supercharging his Jeep and this was a stumbling block so he did a turbo on his old 300ZX instead).
Ah let Tony break it. I was hoping for launch,and a 2nd gear yoke buster. He better get that torqueflight roadworthy Doc have to take that tune out of his ass. Lein on the Jeep,till the tranny is done. Keep driving by his shop,brake torque a 3rd gear tire destroyer with the air condition on,and the windows down.
My way of making it faster would be to put a good old fashioned carbureted V8 in it. There is more to the car hobby than just speed and acceleration. Those may be the goals, but how you go about it is just as important, if not more important. It is, after all, supposed to be FUN. If it wasn't, why would you even bother doing it, other than maybe for someone else, for money, as a job? There is nothing fun about computers to me. I literally despise them. I recently turned 65, and managed to completely avoid them for the first half of my life. They have made the second half of my life absolutely miserable. It's hard to understand why a car person, someone who has been a car person all their lives, and is now my age, would even consider mixing cars and computers. Most "tuners" are young, and into Asian and European cars. They grew up with this garbage. It's all they ever knew. I actually feel sorry for them. They missed out on a whole lot of car related fun. I have one of Tony's t shirts that says "It's Not How Fast You Go, But How You Go Fast" I just ordered a couple more. These shirts express exactly how I feel about cars, and assuming Tony came up with that, and because of a lot of things he has said on his videos, I have to wonder why he would get into computer cars. He actually made a video suggesting that Stellantis build an "electric muscle car" I almost fell out of my chair when I heard him say that. Just a couple years ago, he made a video saying how disgusted he was that someone had converted a '57 Chevy to electric. That totally disgusted me too. Fortunately that particular car now has an internal combustion engine in it again. Sadly it has aftermarket TBI on it, but that would not be difficult to replace with actual carburetor. I would MUCH rather have a slower car without a computer than a faster car with a computer. Again it all comes back to just plain FUN.
Ok boomer. Almost exact same comment like on another video here about ECUs in cars. I think the point is made that someone hates "computers in cars".. 🤣
@@CSI_tuning_solutions Computers are totally opposite to what hot rodding is all about. I suppose that next you'll be saying it's ok to increase performance by swapping the internal combustion out of a car, and replacing it with a battery powered motor? TRASH computer technology is destroying hot rodding. Hot rodding is about a whole lot more than just going fast. It's actually more about the aesthetic. A classic/vintage car with a carbureted V8 engine, loud exhaust, manual transmission, etc. The whole purpose of hot rodding is to get away from the TRASH technology and ugly looks of "modern" cars.
@@geraldscott4302 I don't know where ur despise comes from. We r talking here about an archaic efi ECU from the 90s. Simple efi systems have been around for over 40 years or even older. So it's not something new.
@@CSI_tuning_solutions It doesn't matter to me how long it's been around, that doesn't make it right. Hot rodding is something rooted in the old days. It doesn't really translate to the new digital garbage. Racing organizations like the Southeast Gassers Association are preserving the real thing. They don't allow any car to have technology that was not around in 1967. That even means no electronic ignition. Points only. I never really had a problem with the old school analog electronic ignitions, like GMs original HEI. It's when they started putting microprocessors in it that it became a problem. Hot rodding basically started in the early 1930s, with the 1932 Ford Model 18, and the flathead Ford V8. It was alive and well throughout the '50s and '60s, and then slowly started declining in the '70s, with all the EPA emissions garbage. Carbureted '70s cars still made good hot rods, as long as you did away with the emissions crap. Then it disappeared altogether in the '80s and 90s, with the advent of EFI and front wheel drive, and gave way to the Japanese "tuner scene" From the way you put it, because EVs exist today (but hopefully not much longer) then a few years from now it would be ok to build an "EV hot rod" Not so. Hot rodding is from a very specific era in time, from the 1930s through most of the 1970s. It uses technology from that era. I actually built my last hot rod out of a 1993 Chevy S-10 truck. It came with a computerized V6. I kept the body, frame, and interior, and ripped everything else out. It has a carbureted 383ci small block, a Muncie M21 4 speed, and an 8.8 Ford Trac-Lok rear axle. I removed every single digital part from it. It has absolutely NO emissions parts. It's not a hot rod in the traditional sense, because it's not built out of a vehicle from the right era. But it's fast, loud, and purely mechanical. The same thing could be done with Tony's Jeep, but that's not what he wants, it's his, and he can do what he wants. But he's getting away from the spirit of hot rodding by using computer parts. Simply making it faster does not make it a hot rod. It has to have the "essence" of a hot rod, which at the very least means a carbureted internal combustion powered, rear wheel drive, 2 door, American vehicle. As for my "age" I'm about the same age as all these guys. I grew up working on real cars with no computers, and that's the way it's going to stay, at least for me. People used to ride horses for transportation. People still ride horses, only now it is mostly for recreation. Hot rodding has always been about recreation. "Modern cars are nothing more than computerized transportation appliances, or "CTAs" as I call them. We need to preserve the past, or it will be lost forever.
@@geraldscott4302 I always try to keep an in open mind to all available technology. Old or new. Each has it's right for existence in it's own context. I like old hot rods even it's way before my time but also newer efi 80s 90s . It's also called technology advancements. Need to roll with it or not. Anyway. If it's wasn't for computers u wouldn't be watching this and or be commenting.
Don’t understand why you have to pay 50 bucks? Didn’t you bye this program? Won’t they get in your face now if they think you are doing something illegal? Don’t understand why you have to sign your life away either? This is your program you have got from them?
The software for your computer is free the interface or dongle is a cost and to access computers using their engineering is anywhere from $50-$100 and so on per vehicle for the ability to go in and change parameters and it’s federal emission stuff that they’re worried about it’s the feds not the people at HP
Even with a paid tuner, it's pretty much a standard to be able to program 1 to 3 different vehicles before you hit the pay wall. It seems a little greedy until you actually think about it and the associated costs: The physical tuner and/or the associated software. The software obviously needs to be updated regularly. The servers that host the website and the files need to stay running. And the main two reasons you need to keep paying for another additional VIN: It prevents people from undercutting the developers using their own devices. Why buy their tuner when the local shop already bought one? Secondly it's actually quite a process to read the data from any given make/model...but that's a scanner. If you can change tables and disable sensors permanently, that means they haven't just read the data... they've actually defeated the proprietary anti-tampering efforts and written data to a read-only device. It's a pretty difficult thing to do...in the early days it was common to need to remove the ECU and do a hard-mod or manually flash the read-only memory with your desired tune. Some cars even had aftermarket "unlocked" ECU PCBs that were a drop in replacement for the factory part but had custom firmware you could change on the fly (like Brian's Eclipse in Fast and Furious). Iirc when the C8 came out there were custom twin turbo cars built long before the ECU was cracked.
Thanks!

Part of the Project is that only drag strip ET is a priority. That the car wouldn't be driven on the street.
I get that, but since there is zero benefit, and there is a marginal negative effect, why exert effort to change something just to make it worse?

It prevents people from undercutting the developers using their own devices. Why buy their tuner when the local shop already bought one?
Secondly it's actually quite a process to read the data from any given make/model...but that's a scanner.
If you can change tables and disable sensors permanently, that means they haven't just read the data... they've actually defeated the proprietary anti-tampering efforts and written data to a read-only device. It's a pretty difficult thing to do...in the early days it was common to need to remove the ECU and do a hard-mod or manually flash the read-only memory with your desired tune. Some cars even had aftermarket "unlocked" ECU PCBs that were a drop in replacement for the factory part but had custom firmware you could change on the fly (like Brian's Eclipse in Fast and Furious).
Iirc when the C8 came out there were custom twin turbo cars built long before the ECU was cracked.
