I have a 88 crx si fully built, t3/t4 turbo.... long list of mods. when i throw about 4lbs of boost to it i get a code the car wont idle and if i try and hold it @ low rpm's it runs like crap. if i turn the car off and start it up its fine. i was told by 1 person its the map sencor, that it cant read the boost. can anyone help and how can i solve this?? much appreciated. btw i tried searching but came up with nothing, kinda a comp noob lol

update...
cp pistons, eagle h beam rods, head redone 3 angle valve job, still obd0, turbo link engine management with extra 550 injectors (still lean havent tuned it yet tryin to get out all the bugs b 4 the dyno) t3/t4 turbo, speaco i/c, greaddy type s bov, basically its a new motor.

what kind of management are you using?
Please give us the list of mods

 

updated the 1st post so people dont have to read 10 posts to get the whole story.
would leaning out and obd0 car really throw a code untill i shut the car off?

 

what the hell is Turbo Link?

 

lmfao ohhh yea that was my reaction when i got talked into it by a performance shop, supposedly it is or was what edlebrock was using on thier turbo kits. im prob gonna end up with neptune or something

 

it sounds like a missing link setup. are you using and FMU?

 

no fmu the extra injectors are controlled by the turbo link. i got a post on dseries.org and those guys seem to think i need missing link or check valve. searchin now

 

If your car is shutting off and you have management its not good. the ecu not the map throws a map sensor code. The map can actually read low amounts of boost i think up to ten. But if you are getting your car to shut off while boosting you are creating catastrophic misfires. I learned this the hard way. I know the boost is fun but have it tuned before driving it. To stop the code you can use a map missing link to prevent the boost from going into the map sensor. Just go hondata with ob1 with ecu match to your engine and ditch the old fmu, missing link and rough idling issue.

 

na it feels good gettin up there, its not detonating, just hesitates when the code comes up and will keep running if i keep the rpms up

 

when the stock ecu reads boost it flips. check valve would get rid of the cel. the stock obd0 map read up to alittle past 9 accuratley

 

you're in nj,so hit up xenocron..he can chip and tune your ecu for you so it will run perfect and be setup for boost http://xenocron.com

also isnt turbo link a GM thing? so you have a fully custom made wiring harness? you sure you have turbo link?

 

na the turbo link is basically an extra injector controller, i let some jackass talk me into buying it

haha,,yeah get rid of that crap.., go to north bergen,nj and have xenocrom chip and tune your ecu..

or you could get the fmu setup but cant boost to high otherwise it runs way to much fuel..

 

a map missing link is a check valve used on the map to prevent boost from getting into map and throwing a code. old hks f-con system i think control extra injectors. one word ..... hondata with obd-1 ecu conversion will solve everything. obd-0 is not a good tuning setup its very primitive like my typing skills i'm drunk
