Is this transmission part number backwards compatible? I thought I recently saw 2015-2018 Vette 8L90's have one part number and don't recall 2019 being on that list. I know we ran into unique issues...

You would need access to the vehicle again and then hit gather info. On the ECM's drop down, click on DO NOT READ. This will read the T42 only. I don't see anyway to remove a ECM file after it's all...
What tap shift product do you have? Reach back out to Speartech and talk with me, JUSTIN. Provide an order number and we can discuss your concern. All tap shift products were initially programmed...
Did you pair the ECM and TCM together? Although the 2010+ E38 ECM is required for your setup, you must also get the TCM paired to the ECM.
Post the tune and we can take a look to see if it's under lean/fuel savings tab.
Sorry just saw this. It's either from a Silverado or a Sierra. Not sure which 2500 it came from but I believe it was from a 2500. This was purchased years ago for L8T harness development and I didn't...
Ignore the ECM VIN as we had to have some ECM hooked-up. But this is a 2020 L8T 6L90 read only.
Powertrain Relay is likely needed on this setup.
Good catch, I didn't realize this MAP was for other applications and since the part has the same appearance as LT4 engines, I assumed that it was a LT4 MAP and required the LT4 MAP scaling. I've only...
Map scaling needs adjusted for the LT4 style MAP sensor. See attached picture for reference.
MAP Sensor Linear 425.00 kPa
MAP sensor Offset -32.50 kPa
130857
What MAP is installed, send a picture or part number. I feel like the Eforce uses the T-MAP from the LT4 engines? Not sure if that's correct or if they use the LSA MAP sensor (Red Label).
P0826 is not going to cause issues. This is a background codes that's set to "no Mil" by default. If it annoys you then go in with HP Tuners and turn that code OFF but it won't cause issues.
If you...
See attached stock file that has the transmission OS you've requested.
158MPH reporting is typically present when an automatic transmission computer is being used in a manual application. You need a manual tune in the computer, if possible. I don't know much about the...
The "in gear" idle speed is setup to 0 for some reason. This tune is modified quite a bit and isn't "stock". I would recommend converting back to stock if you have the bone stock file and go from...
You're good with an unlock. I've done several 2019 T87A's for LT1/10L combo's via HP Tuners unlock service.
Does the 2020 Camaro do the start/stop crap now? I'm wondering why they are using the T93's now.
Does HP Tuners have the ability to disable VATS on the E99 ECM for swap use? I don't see this listed anywhere.
Speartech Fuel Injection Systems Inc. can bench tune T43's with a fresh SPS flash matching your VIN number.
Your C5 pedal will work just fine, even with a GTO tune. The service number on the back of the E40 ECM will let you know what year it's from.
Main issue I just read was that you have a 2006 E40 ECM with a 2005 calibration written in it. The 2005 E40 must use a 2005 calibration and the same goes for the 2006! So hopefully this 2006 E40...
You can try a write entire on the 2012 transmission if you still have the original 2013 TCM file. However, if the TCM is indeed blank or brand new from GM, you will probably need factory GM software...
No, VATS will not prevent communication.
Speartech can build you a harness that will match your engine/transmission combination. They will need to supply you with a new ECM and TCM to match your build. Just give them a call. They've done...
Nick,
If you get another 2008 or even 2009 trans you should be able to do a write entire on the trans only. With 3.x software you can skip writing to the ECM and Write Entire to TCM. I would do a...
