TBSS E67 ECM with a LS3 Engine how do I tune this

[nycblazer]

Hello Guys, I need some info and help here.
What I have here is a Stock tune from a TBSS using a E67 ECM with a stock 2008 Corvette 6.2L LS3 engine, mated to a T56.

I have the engine running now but what do I do to tune it to a LS3 6.2L tune, can I put the Files here and someone can tune it for me or do I need to take the truck to a Dyno tunner?

Thanks
NYCBLAZER

No.



Look up almost any LS3 based vehicle and start copying appropriate tables. However, tuning for the LS3 is no different than just tuning any other vehicle with a significant engine change.

You have a T56 in a TBSS?

You have a T56 in a TBSS?

Yes, I am using a 2008 TBSS OS E67 ECM and stock tune, with a TBSS harness.
Now the engine is a 6.2L LS3 stock also.
The engine starts fine no problem but it's not accelerating the way it should.

So what I'm tryig to figure out is how to take or add everything from a stock LS3 tune and add it to the E67 TBSS ECM..

OR CAN SOMEONE do it for me? Is it possible?

Sorry no I MISUNDERSTOOD there, I'm not using a t56 in a trailblazer, but I am using a TBSS harness in a 1999 chevy s10 blazer with a LS3 mated to a t56.

Force MAF only operation and most of the problem will go away.

[nycblazer]

Is the OS from a 2008 TBSS the same as the OS of a ZR1 corvette?
They both are E67 ECM's.

How about post some data we can look at? Definitely interested in your project...

[Roger Ramjet]

Here is a starting point. This is not a great tune but it should work pretty well if you force pure MAF operation.

Ok I got it running and I think tuned to a LS3 now.

Here's the scenario, what I have here is a 1999 Chevy S10 Blazer that I swaped the engine for a LS3 Mated to a T56 tranny.

The engine Harness was custom made to plug and play to my 1999 Blazer.
The engine harness is the same as a 2008 TBSS engine harness. It uses a E67 ECM.
what I wanted to do was use the 2008 TBSS OS and tune and just change over all the LS3 Corvette tune over to the TBSS OS and tune, so what I did was I opened the Stock TBSS tune and then used the Compare function on the HPtuner and opened the LS3 Corvette tune.
I then compared both files to show differences, and from the I started to copy over most of the LS3 tune over to the TBSS tune. I then saved it and wrote it into the ECM and it worked.
It still needs to get tuned by a pro but I got it running much better than what it ran before. It now idles at around 550-600.

If theres anything you guy see that I might be able to change let me know, also Roger Ramjet I really don't know what I have in my tune, but if forced MAF is better how do i do that.

C6Z_sd I posted the data I used and the one I'm using now.
The first one 2008 TBSS stock tune is what I started of with,
the second one 2009 Chevrolet Corvette 6.2L Stock tune is what I used to copy over to the TBSS tune,
and the last tune 1999 Blazer TBSS with LS3 tune is what I have running the engine right now and looks ok for now.
I havent been able to take it out for a ride yet, but its running much better that it was before and also idles better and lower now.

C6Z did you get a chance to take a look at it, just wanna see if it's right.
Another thing I wanna do is to test the electric fans to see if they will turn on. Can I adjust the setting for it to turn on at let's say 100 degrees, just so I can test it?

Nice job with the TBSS tune and the LS3 Vett tune cool

Thanks,

How do I tell the TBSS OS that it not an automatic, it's a T56. I'm having a very hard time taking off on hills. When I press the brakes it won't throttle at all.
