ahh thanks. i was told by a friend that it might be hard to find someone to tune it up after the conversion. is this true. could you recommend a good tuner? morpower perhaps?

what kind of power gains can i expect from this. reading the factory figures, the MPFI model makes 19kw more at the engine than the CPI. is this to be expected.

would the parts for under $200 be from a wrecker?

What do you want to tuner to do? if you want it chipped try Road and Track

For the parts, try u-pullit down elizbuff. IMO taking the mpefi stuff of the car youself is a good start, and you get to pick the best (undamaged) parts. Plus they are cheap.

hi
i dont think there is any need to tune the mpfi other then timing/plugs/leads.ect maybe get the injectors serviced
because as far as i know there is no real way of tuning your ecu
the ecu gets all its readings from the sensors (temp,hego,maf)and it will learn after a short time..

some one else may have more info on the tuning side of it...

please correct me if im wrong

nah your right. If you get an ECU to match the manifold there isnt anything to tune. Suppose you could call setting the timing tuning, but if you cant do that yourself then dont consider trying the mpefi conversion.

ps. i've been wanting to do to my ea what you have done with yours. that is, remove all the rubber and silver trim from the exterior, and those stupid black n grey lines. did you do it yourself?
