I have an 88 crx si, cp pistons 9.1 compression, eagle h beam rods, arp head studs, cometic head gasket, t3/t4 turbo,eaqual length manifold, spearco fmic, greddy type s bov, new motor mounts w/ inserts, wahlbro 255 fuel pump, aem fuel rail, plus more i forgot. when i throw about 3-4 lbs of boost @ it it throws a code hesitates and when i let off it wont idle and hard to keep running @ low rpm's. I had someone tell me its the map sencor, that stock hondas cant read that high. im not familiar with obd0 or older hondas. id appreceate any help i can get. I did some searching but im not that good with a comp so please dont flame me

my bad im using turbo link with extra injectors, which i think is a lil lean. would leaning out the motor throw a code on the obd0 cars?

yes, you definately need something to prevent the map sensor from seeing boost. the factory ecu will go into limp mode and get a CEL as soon as it sees positive pressure

missing links and extra injectors are a bad idea. i would sell the shit and chip and tune your ecu. way more reliable and easier to tune. how are you pulling timing? i would hate to see a 400 hp capable setup blow with less than 250 whp.

whats the best way to as far as tuning for the $$ i had aem ems but the jackass who ordered it bought it for the wrong honda so i sold it and im kinda broke now but i know tuning is about everything. theres a local tuner here who helped develop neptune that i was thinkin about. i kinda wanna go with ems but its soooo much
btw i already have new 550 injectors for it

ill check it out, i saw alota guys r runnin that but i never heard of it. i was thinkin about turbo edit cuz of the obd0 reason, but i might just save up a lil $$ bein as its winter and get the aem
forget the AEM, just use turbo-edit (or run OBD1 and use crome...)
