- Failing to plan is planning to fail, and as a professional tuner, you’ll typically find that most tuning jobs will involve some kind of problem that requires diagnosis and repair before the tuning session can be completed.
In this webinar we’ll cover the top problems we’ve seen over our career as a professional tuning workshop so that you can learn from these issues and have checklists and plans in place to speed up your own diagnosis and minimise wasted time.
0:00 - Introduction
2:20 - ONE: Fuel System Issues
12:39 - TWO: Ignition Misfire Diagnosis
22:24 - THREE: Trigger System Issues
34:09 - FOUR: Common Wiring Issues
38:57 - FIVE: Mechanical Failure
Due to the current global situation we though over the next few weeks we'd help keep you guys out there entertained and release some of these Gold Membership webinars to you for FREE to help pass the time.

I'm just £100,000 away from buying a dyno. Excellent as always
haha yes we know that feeling! Andre did a lot of road tuning before leasing his first dyno, but some good secondhand units do pop up if you keep your eyes peeled - Taz.
Started tuning my Honda and this video has great tips. All your videos are awesome and I appreciate you making them as they gave me confidence to start tuning my own build! Love from America !
Awesome stuff mate!
That lesson made me install a fuel pressure gauge for my rb swapped e36. Seems so logical but never thought about it in the first place. thanks for all of your efforts!!!
Thank you! Much appreciated, love all the information you shared and explained perfectly!
Having a fuel pressure sensor that feed's into the ecu's fuel map is key these day's. FPR's are not truly linear with flow and pressure, so best to ensure the ECU is keeping watch and adjusting things correctly.
As for timing scatter with Nissan OEM CAS's. This is why having an ecu with an on board scope is so important. It makes diagnosis so much easier. More data is more better. Makes fault finding that much easier in all cases. limit's guess work that you don't get paid for.
Another great lecture.

Love the Intel on this video very informative 😍 thanks 🙏
That was interesting. Thanks for that you guys.
Our pleasure! - Taz.
This guy is awesome!
Some great and interesting points. Love your willingness to share this incredibly insightful and useful information.
Holden VS Commodore factory wiring harness, will "work" in a turbo / aftermarket ecu conversion, but after watching the wiring standards set by the likes of HP academy it's almost surprising the factory harness works at all. No emi shielding to be found on any wires, very limited or absent sheaving and powers the ecu, injectors, coils etc all together off a single 18 awg (ish) wire.
all excellent information,zero bulshit.pure logic, A few of the ''tuners''in Ireland could do with doing your course a few times !
Great video man!!
Keep up the good work!
You should do a video on different Dyno softwares, I owned a DYNOJET and then a Mustang Dyno and one of the software is like DOS base compare to the other, I think this would be a great video for everyone that is buying a Dyno and talk about pros and cons of them too.
We have talked about it, but it's such a huge investment for us to do this, and we don't sell dynos so we'd never get, literally hundreds of thousands of dollars, back.
That said, Andre has used a large number of dynos over the years, and Mainline is his favourite due to the software. They were leading the pack when he invested in his first Mainline dyno and still are to this day, and as that is the dyno we have on hand here yes we have done some members only lessons on the software.
Not exactly what you were after I know, but worth mentioning while I was here =) - Taz.

My first import (kinda) vehicle that I had built and raced (and blew up lol) was a 1992 talon tsi AWD turbo I had never even heard of the 4g63 engine and I was introduced and fell into a love hate relationship with it for many years until I started working at a subaru dealership and I was really like for real impressed with them and I heard about this turbo impreza overseas and I was hooked.... I wanted a GC 2.5rs but ended up in a 97 impreza outback sport wagon that I ended up performing a full drivetrain swap on... I was lucky enough to get ahold of a rolled over sti type ra that I was able to get alot of for the time great parts from....
Talk about being kinda lost tho lol this was WAY before places like I wire and resources like nasioc to get information from... dccd 5 speed really threw me for a loop lol I actually drove it to a training course I went to and picked the instructors brain who ended up making more than a few calls but they got me in the right direction.... remember this was right around mid to late 2000
Yes it is easier now than it was back then for so much knowledge right! Even today there is still some newer technology that we're all catching up with though, that's part of the draw to industries like this. You can never learn or know it all - Taz.
My man and exactly why I tune NOTHING without pre checks two weeks prior to tuning sessions.
You have to be a bit ruthless sometimes but at the end of the day it is for the benefit of the customer to not be paying you to spend your time doing anything other than tuning. Most people can appreciate that eh 🤘- Taz.
Much Guru.
Informative on every level of tuning! Dude I wish you could tune my car. I ended up spending around $1700 with a small amount of exhaust work and it still runs like Crap. Aem infinity 6 Supra.
1700 for a tune??????????????????????????????? ???????????????????? I'll change your oil for $500 lmk bud
Just watched this now and seriously considering getting one of your packages. Do I have this right - higher boost pressures are harder to ignite, hence the misfire, but once ignited, the flame speed is faster? Does the same apply to richer mixtures? Cheers
I’d be keen to learn how you can diagnose false knock. Having a hard time tracking my issue down.
Where was you 7 years ago went threw 2 of my engines trying to figure out a triggering problem lol back them 13b engines were easily available had a motec m2r didn't know about the mode 11.12.13.14 on trigger setup and know one knew or wanted to help then figured out rising rising. rising falling. Falling faling. Faling rising. Was a long time ago mabe in the wrong order ,^^
So if someones car fails on the Dyno (customers fault) because of old plugs or didn't tighten the intercooler clamps, do u charge them extra?
This isn't really a yes/no question as there are so many other factors at play, however, if we assume you had the wrong plugs etc causing a catastrophic failure on the dyno, yes, you would be charged a cleanup fee.
It's worth adding though I feel though this is more and more unlikely as many tuners will have a checklist for you to go through before you drop the car off meaning it is less likely to have such an issue, and also a good tuner doesn't start with a ramp run so it is likely they would notice an issue before getting so far into the tune that catastrophic failure occurs. Same for loose clamps.
As above though, there are more factors at play so it really is a situational thing - Taz.
My tuner supplies his own plugs for your car and does a few crucial checks before tuning.
Sadly there is almost never a fairy tale ending in this job 😳 only ones I'd say would be tuning late model Holdens or Ford's with simple bolt ons 😉
Yes it is fair to say the more modified something is and also the more people who have worked on a car can mean that there is more time troubleshooting than you'd like, but with experience comes the ability to see what jobs might give you those gremlins and to discuss things with the owner and allow time for them before you start.
In some cases, you may even wish to turn away the job, or get the owner to complete some changes before touching the car.
This situation is not unique to tuning however, it is really something you get across all trades in some form or another - Taz.
@@hpa101 absolutely
Most common Dyno problem. Believing dyno numbers from the USA 🤣🤣🤣.
re: Plug type - coppers are cheap enough to justify changing them out more often and are less prone to breaking apart inside the combustion chamber. For dialing in a tune coppers have benefits.
I surprised clutch or transmission issues wasn't one them.
They can be issues, just not as common, at least in Andres own personal experience - Taz.
Im into my tune at a shop for $2,000 Canadian & its still not done . So many issues the main one being rf interferance that nobody figured out until i put in a new alternator & converted to hall effect distributor which nobody recommended doing.
Oh man, sorry to hear of the struggle dude. Sometimes some cars are just more problematic than others, and some tuners are also better than others, not to say yours isn't on point.
We try to show good and bad in our content with how expectations and reality don't always align, and it's never fun when it doesn't - Taz.
Who pays 2k for a tune?????? Hey I'll change your tire $1000 lmk bud
@@enhancedphysique6452 it was more than just a tune really, there was a bunch of diagnostics because it wouldn't tune
May car Ford ecosport diesel in mor hp & mor tourq in possible best tuning engine
Surprised you didn't mention cooling system not being able to keep up.
Ahh you mean the guys who ditch the RB clutch fan??? Haha
As Andre mentioned, there is pretty much an unlimited list, these are just his top 5 most common issues from his own experience in this part of the world when dyno tuning - Taz.
Right ? 200 to the wheels on one 250 on the next! Don't go for numbers guys.
Literally had my car on the dyno today and it wanted to run super lean after 4800 rpm. Granted it has too small of a fuel pump (340) and it’s on e85 but my tuner thinks it’s the id 1700 injectors.
Did you get this sorted? ID1700's are pretty big injectors, but there isn't enough information there to really add anything helpful without it being pure speculation.
That said, if you know the pump is already to small and you're running lean in the higher RPM range that would be the really obvious place to start - Taz.
Yes it wasnt the injectors, the maf wasnt reading correctly because it got dirty

Can tell you've blown a few engines in your time 😅
