the reason it acks up when its pluged in is the procom dont have enough advance at low rpms as they should have.Even on stock ecm when you plug in the tps it retards timing at idle.You can fix this by programing the procom to add advance from 0 to 3000 rpms.
Try #1 at 0 rpms then bring it up to +3 at 3000 rpms keep it +3 all the way to the rev limit from 3000 rpms on.
male it a smooth curve from 0 to 3000 rpm.
Hey guys thanks for the responses!
Yep! definitely has a throttle sensor
Hi MikeinVA, I was wondering if you can help me out here.
Yesterday I ended up just keeping it unplugged and chose a different map on the procom. Map#9 - went for a 200 mile ride today and I must say its running pretty freaking awesome. Better than ever actually. Snappy and pulls smooth in every gear. WAY better that the CR specials I had. But I'm interested in seeing if I can plug the TPS and get the same results if not better.
Here is the mapping I'm using (downloaded from procom)
TIMING vs RPM
If I'm reading this right: the advance is 0 until 2500 rpm where it hits plus 3.5 at 4000 rpm all the way through to 6 then peaks at 5.5 at 7200
If I read you right, you are suggesting set the blue dial on the Procom to #1 and then the Timing vs Rpm map to this -correct?
Also this was the other setting in map #9 - any idea how this setting affects anything? Should I modify this too? Or it was probably doing nothing since the TPS wasn't plugged in...right?
TIMING vs TPS
Thanks in advance! Really appreciate it
