first off its like 1:30 A.M. so im tired if it doesnt make since im sorry

how am i hitting 15 lbs on stock map?
i was runnin 10lbs off of my turbonetics wg then the other day i put my boost controller on and was messin around and i can hit 15lbs no problem im using a autometer boost gauge

so what im askin what is it gonna do it u go over like 11lbs on stock map...make ur map sensor take a crap? im also runnin crome.

my setup 89 crx dx
built b16
t3/t4 57 trim

should throw a Check engine light

gettin it

Did you check the boost settings for the map? You can fool it a lil bit.

why?


OP, your stock map sensor can only read a max of ~11psi so when you are hitting 15psi your map is still reading 11psi. it doesnt know the difference. this can be bad because you are adding more power but the map is still adding the same amount of fuel and timing.

so basically you can add all the boost you want but you cant TUNE a stock map past 11psi

To give you the results of the above answers - it will run lean (if tuned at 11psi, not 15psi) and run too much timing (unless tuned very conservatively), resulting in DETONATION.

If you enjoy melting pistons and junking entire motors, keep boosting at 15psi on a 11psi tune.

scoop up a gm 3bar map or something else thats better than stock so u can have your car tuned for more boost..problem solved

Exactly, I was tuned for 10psi on a stock map sensor and was using a internal WG at the time and spiked to 15psi for about 5-8 <U>seconds</U> and I melted the crap out of my #3 piston(granted it was stock internals) but you should pick up a 3bar. In comparison to the cost of your build, its cheap insurance.

thanks guys..

and i know what its like to [freak] up a motor i broke every ringlang on every piston before i built it and it lasted 3 days on stock internals

and i have a GM 3 bar sittin at home just havent installed it yet im gonna get it tuned at the beggining of next week to 15-18 lbs

also it wasnt throwing a cel

dpetro1

its not gonna throw a CEL. a stock ecu throws a code for positive pressure. chipped ecus eliminate that because they add positive pressure columns to the fuel and iginition maps.

like others said. if you want more boost, add a 3 bar and get it tuned

well got good news i did a compression check today and everything seemed fine 180 across the board so no more boosting 15lbs till its tuned
