i have a 95 h22 a closed deck,we melted a je piston screwing around with the aem ecu.we were tunning under boost using a 2 bar map sensor map and i did'nt know i had the wrong map sensor which i did'nt find out until after i blew that piston,i had a 3 bar map sensor anyway to make a long story short the 3 bar screwed up the ignition and the fuel maps and added too much timing under boost.i work at a machine shop we normally work on big blocks and small blocks,should we do the same steps resleeving the block like we would do on a v8 or is there a speicial technique.i did a search here and i cant find anything,oh yeah the sleeve im using is the darton insert looks like a factory sleeve."poison do you have any sugestions or links".thanks danny
