Now im not sure if this is a transmission, tune or electrical ussie so sorry if the post is in the wrong place.
I've done 99% of my auto to manual conversion car starts and drives.
in the car i have bigger injectors, fuel pump, valve springs and intercooler.
-ECU changed to a manual 6 speed one out of a BA
-6 speed installed with new heavy duty clutch + flywheel
-Manual tailshaft installed
-Pedals installed and hooked up
-clutch fluid reservoir installed
-shifter installed and selects gears fine
-speedo cable from a 6 speed is wired into the 4 speed loom and works fine
-reverse lights from a 6 speed are wired into the 4 speed loom and works fine
-neutral switch is bridged so i can start the car in any gear and works fine
-rest of the automatic wires are not plugged into anything or bridged onto each other.
My issue is that the car will NOT go over 45km/h!
The car runs 100% fine, idles fine and accelerates fine until 45km/h and it will not go over no matter even if you drop the clutch.
NOTES: I had a custom tune on the old auto ECU and unmarried my SCT Tuner from that and uploaded the tune to the manual ECU SUCCESSFULLY, would that have an effect on it since it was done when the car was automatic causing it to not go over 45km/h?
When i flash the car back to stock using the SCT XCAL 4 it will barely idle will barely accelerate, backfires and smokes bad! (this may be dew to the injectors not being able to go low enough to suit the stock tune not 100% sure)
I had 3 guys come out and reprogram the ECU to the immobilizer and PCM and it went fine they all hooked up so i doubt that is the issue
I tried different ECU's out of a 6 speed manual BA turbo and had the same issues.
When i use an OBD II to scan the car it comes up with issues relating the AUTOMATIC transmission f.jpge.jpgd.jpgc.jpgb.jpg
NOW my questions are. If there is a MANUAL ECU installed and hooked up to the PCM and BCM how is the OBD II coming up with automatic issues???? is it dew to the custom tune being from an automatic? Or are they coming directly from the PCM meaning its not hooked up properly and thinks its an auto still? Also what is the deal with 45km/h??
