tuning chip question....
hi all...
does a chip- for example-hypertech, or etc, work with a hotcam??
i want to remove pre and main cats and put on muffler elims on a 90 manual 6..so, i will get code 32..
are there chips available, where the egr function is eliminated??
answers would be nice..
thanks :cheers:

It will work, but probably not work well enough. You're probably going to want to bump your idle up a bit, and I don't believe the hypertech can do that.

Best bet would be a custom Chip. I honestly don't even know if Hypertech removes the EGR or not. I drove my 89 for a year with no EGR (miniram) but never set a code (EGR still was set in the PROM)
If you gut everything in the exhaust.. you will probably need a heated 02

hi..
if i need a heated o2, do i have to change any setups?
as i know, there are three cables..two for 12V+ to ground, one to the ecm
i think, its a normal o2, just with a heating element in it..
how did you disconnect the egr?

I basically removed my AIR pump and EGR stuff. all of it was blocked off.. and it never set a code..

Re: tuning chip question.... (-=Jeff=-)
I could be wrong, (cause Im way out of my league posting anything on this section) but, if you need to turn off the EGR or any of the emissions controls, I dont believe that any of the across the shelf chips are going to help you. It would have to be one that is being sold "for off road use only"

Re: tuning chip question.... (corvette90)
If EGR was ever 'disabled' in a non-custom aftermarket chip, they would likely go about it all wrong. To save their butts, they would probably only disable the flag, but the fuel and spark curves would still be set up for EGR driving. The EGR should not only have the flag disabled but also be regulated to act only at extreme temps (ie a temp that your engine will never see). If the max value is 255, I set it at 253 just in case there are any code glitches for max variables. This would of course be for off-road use only...-Matt-
