Thank you for taking the time to help me with this. I have a 2000 lude with a 95-96 jdm h22a engine installed as well as a recently installed revhard turbo kit. by and extremely reputable and knowledgeable shop whom specializes in hondas. My stock 2000 ecu is still in there and I believe it is malfunctioning and so do they. The car ran well when they just installed the engine (I drove it for a day then dropped it back off for the turbo kit to be installed). With the kit installed, the car runs pretty crappy. As a short temporary fix until I have them tune it, what do you guys think about getting a chipped p72(they recommended that as well), with a base map for my set up. There is a reputable guy on ebay (100% feedback for plenty of honda ecu base tune sales, happy customers). He can chip a p72 with a base map for my set up and get pretty close he said to what I need, and at the very least have it running better than it is now. They retarded the timing 4 degrees because it was misfiring as well. Any info or opinions would be great. Thank you again.

 

Well, if there was no management attached to the ECU and you went with the FMU that came with the kit AND put in larger injectors with no missing link check valve, the ECU is going to act very strange and not respond well. You need to state what engine management you plan to use before getting any "chip" to basemap anything.

Your reputable shop is correct, an OBD1 P72 would be best to use for the prelude (assuming you kept the stock intake manifold), but since you must get new equipment anyway, instead of just using a basemap "chip", get a good managment system that can work with that ECU and tune (calibrate) the whole engine setup properly.

get your p72 and put some good tuning software in it and it get it tuned right. basemaps are to get it to the tune shop not to drive it around for a while.
