b16a turbo problem
 

info first:
2000 civic si
b16a engine
6266 t3 v-band presicion turbo
38mm wastegate
hondata 4bar map sensor
snow stage 1 water/meth system
mac boost by gear system
victor x intake manifold
id 1000 fuel injectors
,,,thats all info u need i think need more info ill post

so i reached a dead end and dont know what causing the sh** im having.

when i drive the car and its about to get boost rpm drops all sudden engine keeps running but not speeding any further no matter how much i increase throttle,,i was having this issue few months ago but it was coming rarely and the issue go after few mins of driving i thot it was the water/meth system getting the engine to cold or sum so i never gave it much of attention..three days ago the issue happened again and not to stop its happening in every gear,,if engine cold or hot,,throttling slow or fast,,no matter what i do its not stopping,,,so i done an air leak test,,check the map sensor,,,check the wastgate,,injectors,,boost by gear system,,turbo,,all is good i even thot of shutting the meth water system but there is no need since meth activation point @(5200rpm) when im even not reaching 2500rpm in every gear :mad: ...

Re: b16a turbo problem
 

Was everything working before the boost?

Re: b16a turbo problem
 

yea and it was working fine with boost to

Check the parameters in ur tuning software

Re: b16a turbo problem
 

So it turned out to be the tps one of its wires was cut off cuz heat I quess! After i changed the socket tried to adjust it and turned out to be the sonsor is faulty it was only giving a max 20% reading I changed it and now car is working so smooth and I can ride in the hardcore way again,, hope this help sum1 that well hv this issue in future.. ohh but w8 I hv a question whay the hell check engine never lighted on,, ecu havent giving me error codes 2 !!.

Good going.. Way to use a nice "low tech" approach.

Re: b16a turbo problem
 

This might sound stupid but the bulb for the CEL in the cluster can be blown. I've seen this happen many times.

Also if it was only a tps issue and the voltage the ecu saw never went out of range then it wouldn't throw a cel in the first place.

Re: b16a turbo problem
 

cel works for 5sec first i turn ignition on and i have removed fan switch to check if its working and it was working fine,,,i c what r u getting 2,,you can c it with datalog but still they should make it give a cel when a sensor that important is not giving a good reading,,just an opinion.

Re: b16a turbo problem
 

to the ecu the reading was fine. hence no code.

if the voltage went out of its 0-5vdc range or didn't get any voltage at all then and only then would the ecu throw a code.

what engine management are you using?

Yeah I recently found out the tps I thought was ok os faulty. Plugged in s300 and found put it maxes at 63% and the scaling from 0-63 was jittery and glitchy as hell. Swapped throttle bodies and now its good. (Other throttle body has the factory screws, I didnt wanna cut them)

Re: b16a turbo problem
 

s300 in a p91 ecu

Re: b16a turbo problem
 

my throttle body works fine but im still thinking to change it with blox 70mm,,now im running with what we call here type-r dont know what is the right naming to it lol..

Re: b16a turbo problem
 

my new tps gone bad again that fast!! the only thing im thinking is the meth/water mixture,,can that be the cause guys? if so is there a solution to it.
