OK, i've got my PFC installed a couple of days ago, everything runs great, boosts great, loving it... except my idle...

I've tryed several times the "learn idle" stuff with the car hot or cold and etcs and no luck. I've had more luck tuning the idle myself (adjuting the screws) then leaving it to the PFC. Acutally, if i don't let it learn, it idles great.... lol i just don't feel like reseting all the data everything i go for a drive....

But possibly, the main problem is that since i installed the PFC, everytime the car is in idle, my speedometor starts reading (and im dead still on Neutral).
My speedo and the PFC reads that my speed is between 20 and 40 kms/h (it changes has the idle changes... )

I've installed a euro kms/h speedo several months ago, but this didn't happen on the stock ECU so... WTF?!

I'm going to install the stock on again later today but..... really... WTF?!?!?!

any thoughts? I really like my km/h speedo....

 

Ah, sorry... my car is a 93 touring (USDM) with downpipe, cat-back, intake and Air-pump removed.. (and PFC obvious)

 

Check your water temp corrections for the erratic idle. As far as the reading on the speedo, I wish I could help you out. It's not a cluster problem if the Commander reads it, so your problem is behind the harness. Good luck!

BTW, do you have an auto or manual?

 

I'm manual

actually. it was a cluster problem.... i tried swaping the entire cluster back or just the speedo and it only happent with the EURO speedo.

Have the stock speedo (USDM) back on and everything worked perfectly. Idles great... no more the PFC reads more then 0Kms/h when im on a dead stop, nor the speedo...
