Thanks for looking out!

Yes I bought a E38 for a Camaro because as I stated in the original post I am running a manual transmission because it was the only way for me to get parameters like vehicle speed since it is in a...

Thanks Blindsquirrel I will give that a try... Thank you for all the help!

07GTS, thanks for that input... I made that change and I am sure that will help me in the future...

Blindsquirrel, Yes that is correct. The only thing I forgot to mention is I am catless but in my...

Hi Y'all,
I have a L96 with a E38. I did had to do this due to using a manual transmission. Engine is running as a standalone with long tube headers, no cats, and cold air intake. I have the...

When I was using the E78 ecu I just had to lock both fans on all the time. To the best of my knowledge it's still not fixed. I currently am running a camaro ecu since I have converted my 6.0L to a...

That makes sense...
I could have sworn that I seen someone in the forums previously changing the OS of their ECM but then again I could just be crazy!


Thanks for laying it all out there for me....

Where would I find the new OS then? In the Tune Repository? Or is there another way?

Also once I have it, can I just re-flash the entire ECM and it not get super upset?

Jon- My intention was not to seem like I had a shitty attitude. Like I said previously I do enjoy learning and even just in your last message I learned about the black connector being the same. I...

5FDP- Do you have a recommended website/ place to find a E38? I just would have to re-pin at the bare minimum correct? I am not super stoked about the Harness prices..

Also, I would rather work...

I know there are a lot of threads out there with the 158 MPH reading.... Not a lot of those are running a E78 ECM. It is quite different from the E67 or the E38. Also I would rather not switch ECM's...

I realize this is an ancient post, but Del if you have a tune handy, what were your speedometer setting in HP tuners? I have a different engine running the E78 ECM and am trying to use a 2 wire...

Hey y'all,

I can't figure out what it is I am missing here and looking for some help. I have a 6.0L from a 2012 gmc Sierra. Its set up for standalone since its mated to a NV4500 Manual trans. I am...

Hey yall,
I need a guy that can actually explain what some of the values in the E78 ECU are meaning. Mostly in an effort to get the Speedometer working so I can do idle tuning. As a side note, I am...

you need to make sure that your VATS is disabled other wise the ECM will be looking for the BCM and the BCM is obviously missing so it cannot send the correct signal. I am running the same set up...

I have seen a number of people including myself dance around this subject for quite some time. Engine is a L96, 6.0L out of a 2012 Sierra 3500 cab and chassis. Are there any good answers to getting...

That makes a lot of good sense. Thanks for the clarification!

Hey guys,
Maybe I missed it, but on page two you guy talk about tuning the MAF After the VVE. Is there any reason as to why to do one before the other? Also is there a good write-up that either of...

I did just read in a different forum for a little older LS2 with the same type of programming type that you need to program it so fan 1 does not come on before 192 degrees. So I changed around my...

Well it would seem I got a little ahead of myself. I found a way for them to either be on all the time, or not at all. I think the logic is broken for the ECT desired %. I can literally set the 0...

I know this is an older post but just wanted to give you couple guys in this exchange a shout-out. I just read through all 3 pages of this and I just fried my brain learning this process! Even as an...

I will try that and see where it takes me... I could see the MAF curve helping but I haven't spent a lot of time with the VVE stuff yet so that will be new for me. I may have some questions come up...

This is the one I have...

Its in a 4 inch tube which I believe is the same as stock....

I also made sure its more than 10 inches away from the throttle plate because that is what GM stated in...

I agree with you 5FDP, I put a manual gauge on my fuel rail and its solid at 58 PSI and I have checked my tune against other "stock" tunes in the repository for the same engine and they are identical...

Alright guys,

I need some help... I have been pulling my hair out on this one for a while and I can't seem to figure it out...

I have a 2012 L96 6.0L out of a Sierra 3500HD. Cold air intake and...
