I need to tune my OBD1, so it has to be sent out because I don't have the proper tools for the upload.

So, if I install the OBD2 back in for a week... 2 things

Will the stock tune on the OBD2 hurt anything on the new valvetrain driving it around for a week?

2nd, will the uninstall/reinstalling of the PCM's hurt anything?

 

How about you take the computer out a week before you are going to need it (ie the car running again) and use the OBD2 computer on the stockish engine rather than the cammed engine?

 

Its to late for that, car is going under tomorrow morning.

I thought about the tune too late...

 

You will be fine with the OBDII for a week. It will really make you appreciate the difference between a stock and cam tune.

The car will be fine though.

Swapping PCMs does not hurt anything.

 

What are you getting done to your car?

 

Replacing my entire valvetrain

XE 227/233 Cam with a .560/.569 lift
OEM Chain Assembly
Comp R Lifters (875)
Comp 1.6RR (1318-16)
Springs (EX612)
Pushrods (7.20 Hardened)
Gaskets and Seals

Car should REALLY wake up after this install

 

Yup, car will be fine. I have to put my obd2 pcm in for emissions. Runs like crap, but it will get you around.

With my stock tune the a/c just about stalls the car.
