Another reason why the LS engines were used is because the NA ECM from the Solstice is able to run the engine and there for makes it compatible with the BCM. This takes care of the large issue with...

OK so first we need to correct a problem with how you are deciding on what engine to use. you need to use a 90? engine not a 60?. you will not be able to get the 60? to fit without having to cut up...

II am not sure what or how the throttle is controlled on these ECM's. It appears to me to be a smoothing algorithm to remove small fluctuations in the drivers foot. It has been known for as long as I...

The problem with the Toyota vehicles was driver ignorance. This driver ignorance did uncover a flaw in the design of the Toyota's. The brakes were made to small to stop the vehicle in the event...

The throttle response is how it normally behaves. This is nothing new. It was there with the stock flash and it is there now. Nothing has changed.

Here is a video that shows the throttle response, This video is for a 2.4 N/A and not my vehicle. This gives you an idea of how slow it is. In this video the accelerator is being mashed to the floor...

You are going to need an in tact engine harness, and you will need a Bosch E69 ECM. Preferably one from a 2008 Solstice GXP.

@EFIHARNESS is correct.

I am going to explain how the starting system on a Solstice works. I own a 2008 GXP and I have some experience with the electrical and also the data systems in the car.

Thank you @10_SS, I didn't think I was imagining it, I was starting to worry there for a minute. It drive me crazy having to wait 1-2 seconds before the car responds to what I am doing with the...

I can't go back to the stock tune because of changes that have been made to the engine performance wise. The car would not run properly.

There has always been a throttle response problem with...

OK I attached the tune file, a log for that tune and also the scanner layout and channels files.

The 5-6 second throttle response issues are when I let off the accelerator, The ECM actually...

I would like to know if the devs over at HPT have thought about adding a feature to adjust the accelerator pedal input smoothing?.. I am pretty sure that there is a buffer of some sort that holds a...

I have some logged data I can share. This is from a 2008 Pontiac Solstice GXP Manual Trans

I have a 2008 Pontiac Solstice GXP and the VCM Scanner is not showing all of the channels that are available from the vehicle.

I have found that with GM using PIDS 0x00, 0x20 and 0x3F on mode $01...
