The ASA engine is an LS1 with the ASA (226/236 .525/.525 110 LSA) cam. GM sells an LS1 ECM (part number 12480054) calibrated for this engine. Is this ECM readable by HPTuners?. If it is, could someone put this calibration in the HPTuners bin repository? I think it might be very informative to see a high-performance tune approved (if not developed) by GM engineering.

If it is authentic It is not readable with hp. You would need to enter a different key than that standard one. In efilive you can manually enter keys, so you would just put in the correct key.

There was not alot of things changed in the calibration.

It is locked....in otherwords, it has no VIN in it. Ken at LS1edit unlocked mine for me.

I have the tune in LS1edit format if you want it.

Or I can post the tables in a spreadsheet

send me a PM

They do have a vin in the place where it should, it just says GM ASA, That is not how they locked it. It just has a different seed/key algorithm than stock production controllers of that type. The Computer itself dont care what the vin number is and the ecm can be read no problem with efilive no matter what the vin is..

Dave F

OK, in my situation, LS1edit wouldn't read it. Ken put a real VIN in it for me, and it worked.

So technically I guess it wasn't "locked"

There is nothing special in the tune at all, The cars didnt run well with the tune it had. Im not sure if i can give the tune out? The only software it would read in would be efilive as the checksum is invalid.

I can read it out for you. I know the guys that tuned them. They didn't leave to much on the table, but there are a couple of things that can be done better. Main thing to do to them is increase the rev limit. I do know they spent alot of time on the speed density stuff. So it will run as long as it is kept in the same config. it was ment to be in.
Is there anything in particular that you are looking for?

Mark, the tune is set to be 100% Maf, no ve tables are used anymore in the tune. They did make changes in the main ve table but that dont change anything in that tune.
Also if there was a maf problem, it was bad, because it would revert to the backup ve table instead where it just went death lean while driving @wot.. The Max Maf limit would be hit sometimes if they cheated causing this issue.

I have 17 actual asa pcms from the racecars in stock here. That are untouched/unmolested straight out of the cars. Pm me if you are interested in one.

here is a spreadsheet with the ASA VEtables and spark table. I agree with above, the VE tables aren't really usefull. Race cars never "learn", since the battery is constantly disconnected, and the closed loop functionality is completely removed by setting the activation temp higher than an engine can run (and survive).

These tables also use the LS6 style MAF sensor, and the spark table is quite advanced. Competitors in our series actually found the advance was so great that it created a lot of extra heat in the engine while only helping power marginally.

here are a few of the tables if you are interestd

Thanks David!

I have Dave Farmer's tune (thank you Dave!) from when I started tuning the Grand AM Cup cam. I have it in both EFILive and HP Tuners. PM me your email and I'll forward them. They really have nothing special, as Jesse said, except the correct tables for the Bosch/GTP injectors.

Cheers,

updated the spreadsheet with Injector table & PE table. The ASA engines (as well as us roadracers) use the GM Trans-Am Turbo injectors.

Dave F

here isthe injector part number, I think

25519365

I think the injector number is 24508208

Dave F

you listed the 87' Grand National version, I listed the 89' Trans Am version. I thought they were the same, but maybe not????
