Hey guys ive searched the web quite a bit and cant seem to find the right search words to find my issue and thus am here.
Background:
Car had a 1jz with 2jz jdm aristo ecu and harness to match and was lightly tuned on an apexi neo. The car worked fine until it showed signs of a BHG. Deided to go with a 2jz bottom end and Sent car to a mechanic friend of mine to get the 1.5jz into my 88 mk3. We decided to change the harness while we were at it ( got the harness from tweak) now after putting it all together, we plugged te neo and it is showing a tps signal of 100% even when the engine isnt running but the key is in the on position. Turn the car on and still the same. I tried a different tps from a 2jz and still the neo is reading 100 on the tps signal. Additionally the car stalls and seems to not want to rev when i press the gas pedal hard. The car does idle at around 600 rpms which also seems a little low based on what i have seen. Previouly it idled around 900hp.
