It’s a manual, I’ve never owned an automatic car.(if you don’t count my wife’s)��

I am going to attach a copy of the tune im running when i finally got it going today it feels a little off in the cams power range compared to the...

Welcome

When it comes to tuning, I have done it old school, seat of the pants, vacuum gauge and listen for knocking. I have worked with fuel injection over...

Welcome to the forum. It sounds like you're on your way to figuring out the issue with your motorhome. $42 is one of the best supported GM ECM's....

Hello, Those can be pretty quick cars. Manual or auto?

Hello! What are you you working on?

Hello and welcome to the forum. OBDII info can be found at https://www.gearhead-efi.com/Fuel-Injection/forumdisplay.php?32-OBDII-Tuning

It's surprising how many differences exist between the two calibrations. In some spark tables it looks like values were set to mimic the original...

can kind of remember reading the MAP TPI's have the non-adjust TPS, and at key on the ECM reads the TPS which can be between .3 and .9, all the other...

No, I don't have a knock sensor, just something I saw as I was looking at all the different tables. I'm looking forward to seeing how it does. I'm...

Are you using a knock sensor? If so I can move the knock tables over.

Has anyone heard from Carl / InTech lately? It looks like he stopped posting on forums about a year ago.

Riddle me this! The only way I can get my truck to run decent is to zero out the spark biases. My initial timing is 0, I'm running at 28deg at idle...

I discovered this yesterday. I adjusted my curb idle screw to obtain around 25 counts on the IAC and it ran the TPS up to .68V, the FSM calls for...

Removed the ICM, and measured resistance between P and N per diagram should be around 10K, but it's open. Is that test proper? Bad ICM?

Yes, under the rotor.

is the module inside the dist under the rotor? there is 12V on the pink pins on the injector connectors with key on, when in crank, voltage drops...

No distributor reference pulse (DRP) will cause a no start. The DRP comes from the distributor ignition module.

Yeah, I just used the following for it to run way better than it was running. The no vats one is the one i modified to account for DTCs and no cats....

The LQ9 never came with a 4L80E behind it. Will need to segment swap to create a tune for that pairing.
