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 ...

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)
