Thank you so much!!

Thanks for the quick reply! The service number is 242521140060, but if you are saying that all of the TCU's from those years can be flashed with the correct calibration I should be good. I'm not 100%...

Hey there,

I've got a 58x L77 that I'm building and want to use a 4L80e behind it. There is a guy locally that is selling a E38, harness and TCU with a part number of 24241806. I can't seem to...

Did you ever get an answer to this @HCCPerformance ? I have an original MVPI Pro and would like to update my 2015 F150 for the bigger tires.

So I finally got the courage and with the weather cooperating last night, I revised my VE table based on the logs from LTFT. I was having issues with the car surging under light throttle at just...

Would you be willing to share the tune file? What ECU did you tune it with? older ECU or the 0411?

So, I think I may have found out what is happening. When I copied the tables over from the 01 Z06, I only copied over the primary VE table. Since the 01 ECU doesn't use a secondary VE, I never...

I'm just getting my car up and running and I'm hoping to find someone that may have a better tune to start with. The car is a 1968 Camaro and the motor is an LS1 short block, but has LS6 intake, LS2...

Hi guys,

I'm working through a similar issue on my LS swapped OBS Silverado. I'm running a 2002 Silverado 0411 PCM, and the motor is a 06 LQ9. I recently swapped the truck over from a clutch fan...

I should also mention that I have an LC2 wideband that I plan on plumbing up shortly when I finish my exhaust so I will have the ability to create an error log PID. (I think that's the language). I'm...

Here are the logs

I was able to get my cam sensor wiring figured out by swapping the outer two wires! The code went away and it fires right up now without cranking for several seconds while the computer figures out...

Thanks for this detailed advice! This will be extremely helpful to me once I get the cam code resolved. Good to know that is what is causing the open loop condition.

Hi there,

I just finished up building my budget LS6 using parts I have gathered over the last few years. The motor is a stock LS1 shortblock, LS2 cam, 1x front cam sensor conversion, 799 heads,...

Thanks for the responses. Yes, I am using a modified 02 truck harness that I re-pinned to match the LS1 ECU. I currently have the two high/low trigger wires coming from the ECU to trigger the fans....

Hi there,

Thanks for the reply, but I'm not entirely certain what you mean? I currently don't have the fans hooked up, but was planning on using a typical 4 or 5 pin relay. I was also considering...

Hi there,

I searched for a while last night and today and can't seem to find an answer to my question. I thought it would be fairly straight forward, but for some reason it doesn't seem to be...

5FDP, Thanks for the quick reply! I should have mentioned in the first post that my buddy said that this motor and the current "tune" were done by a shop for that specific combination. However, I...

I am in the middle of a complete restoration/LS swap on my 1968 Camaro. So far I am to the point where the car can be successfully started and driven. I have run the car several times now and I...

Sorry if this is for the wrong section, but is the segment swap only for things like transmissions or will this work if say I am trying to convert from DBC to DBW?

The reason I ask is I am trying...

Hey guys,

I have read through the stickies and they were very helpful. My first question is in regards to the actual HP Tuners program. I am looking to compare two tune files and see what the...

I did have the intake off in order to clean all of the grease and grime off the car. I sprayed all of the vacuum ports with starter fluid, and it didn't raise the idle at all. I took off the IAC last...

Here are the files

Ok, so I went through my engine this weekend, and looked for vacuum leaks by spraying around the intake with starting fluid. I didn't get any increase in idle on any of the vacuum ports. I especially...

Hi guys. New to the site, and new to tuning and looking for some help. I recently started up my project after doing my LS1 swap, and now it won't idle under 1200? I am unsure if it is a tuning issue...
