This video helped me figure out that my cam sensor had an issue and not my crank sensor. My cars first 50 miles were great but then I mysteriously developed a rpm sync error that cause the car to fall on its face at random times mostly near 3k rpm. I checked everything with the crank sensor wiring and replaced the sensor with no luck. Everyone said it was either my crank sensor, reluctor wheel, or thrust bearings. I couldn’t settle for the idea of it being a hardware issue on a brand new TSP 14k engine. So I looked at a small diagnostic log that showed I had 0 #7 events and 120 climbing to 130 #6 events. This gave me a strong lead to check my cam wiring that I had extended since Holleys harness was about 8” short of reaching the front cam sensor (wtf Holley!!). Either way I had taken the extra slack in the cam wires I extended and tucked it up next to the alternator to make everything look good. The EMI from the alt was causing the errors since I didn’t run extra shielding . Once I moved the wires away from my alt the logs show zero errors!
This is great. Well freaking explained. I have an ongoing issue with my Ls1 , and me and my tuner have not been able to figure out what the problem is. The car only bogs right off the line WOT or when rolling on the street then to WOT. I send him a full datalog of when it happened and his suggestion was to start by replacing the crank sensor. I did replace it but have not been able to drive it again due to rain and stuff here in Jersey the past 4 days. I hope that fixes the issue.
Took the Holley, Dealer, V1, V2, and V3 classes and this video is almost more help than those. Certainly more with Diagnostics types, luckily I've not had many issues with this and mostly use the RPM going to error to find the problem. Terminator X software doesn't go offline when you cycle the key and keeps trying to connect to the ECU while off, so it locks up when you shut off a new motor and go to check things or because of an issue. I tell everyone you called it Terminator because you have to open manager constantly and Terminate the software. This also kills a troubleshooting task we used with customers on the phone to see if they are losing power to the ecu. Would really love the 90's technology of selecting the folder where the Holley software works from instead of always in Documents. I want to be able to put it into a Dropbox folder or Google Drive folder. Right now you have to copy it there and if you want instant access to everything you need two copies of that on the drive. Been using this since V2 so I have about 30GB of old tunes and logs now.
Good stuff. It lead me to the issue I had, but I wish you would've included Diag #4, when I found that and compared to the rest it verified a lost cam sensor signal.
Hoping you might see this, as the advice im getting from holley techs and tuners has not been helpful. new setup, and on startup it runs terrible with a rolling misfire. datalog shows diag #7 stable at "1", but Diag #6 has a very odd signal, going from 0 to 1 and back to 0 2-3 times per second. Ive completely checked the entire harness, pulled the engine to manually check timing and physical components, and went together with new sensors, new coils and even swapped injectors with no resolution. Any ideas on what could cause this?
Hello I’m trying to figure out an issue my truck just started. I’m losing crank/cam signal at higher rpm speeds. Truck starts and runs great other than that. Looking at the log Diag 6 goes from 0.00 to 1.00 and Diag 7 goes from 0.00 to 2.00 both happening at the same time. Have any suggestions?
What was bad with the wire? I’m having issues starting mine and it’ll crank and run for a few seconds then shut off and will backfire every now and then. The cam sensor is red but crank is green
Can’t get mine to fire up either. Will run off starting fluid with only the crank sensor plugged in, won’t run when you plug the cam sensor back in. Really weird. Have fire and fuel. Must be wiring, signal or programming errors. Can’t figure it out!
Im having an issue where it won't even start .it back fires and pops like the timing is off .I confirmed the cam gear is lined up and the valves are not hanging open. .can I log cranking
Hello I’m having Trouble with my Terminator X each time I wanna start it up the truck misfires or backfires and it’s always shows blue then red on 6 I Already replaced the sensor what can it be?
The video was done using Holley efi software for HP/Dominators. All the info applies but the instructions are different between the two products. You just need to install it he Holley efi software and you reference the help in it.
I have issues my set is a l99 motor I removed the vvt I install a stage two c am with a 4x cam wheel . When I try to start my motor it go stall syncing back in forth . Number 6 stay blue but number 7 go blue green bulge green . But if I change my 58x to 24 x the rpm’s go to 180 I bought brand new crank also brand new cam sensor from the dealership acdelco I check everything I’m getting all the power it needs 10.45 volts while cranking
i have a holley hp and did cop. just got a efi connections x58 crank trigger and cam sensor. this vidio has helped me some. cant get cam or crank sensor to show 1.00 both show 0.00. in the datalog it shows 100.7 kpa in diag6 and 29.7 lb/hr. what am i missing? i efi connections was no help. told me to call holley I have it set up in ignition lsx58X not custom. any help before i burn it to the ground? thanks

I've got both V1 and V2 versions of X Max and I cannot find this diagnostic info anywhere in the new help files. Holley's tech line is so overwhelmed with calls that that have an attitude towards customers assuming we're the problem. At some point I'm going to do any outline and call in to my contacts upstairs and try to get them to understand that they have a lot more work on this software to get the average user up and running. We have a brand new Wegner blown 416 engine (30K) that has been dynoed and suppose to be plug and play. We have no rpm signal and no one in their organization can solve this issue. So that's why I'm trying to learn as much as possible to debug the error. I've done three X Max installs and they all have issues. Start with a base file and then work on the learn or just take it straight to a dyno and work through the data to get this stuff squared away. I do not like the whole logic in their approach and I especially don't like the harness, which has no labeling. Next time I'm going to point thumbs down on their product and use the GM factory stuff. I may have to deal with licensing cost and HP Tuners, but I can get a better result quicker.
@@highperformanceconsulting7616 thanks for the reply. Making boost, but less power than expected. Just going through the check list while i wait for boost leak testing parts. My logs look good through range of rpm. Great video

So if I'm understanding this correctly, if diag #7 reads 0 constant while diag #6 reads various (from 1-10 in my log) then I have a fault in wiring or a bad sensor? Odd to me that I can get it to start without crank sensor.

We have been making some improvements to the Terminator X USB communications. It should lock up much less in a future update.
Thanks for the video. My car will randomly run horribly, and then sometimes it'll instantly be fine. Now I can check to see if it's cam/crank.
