wait - so this is a TII?

a bit more info would have been nice from the start.......

I would first check your TPS settings, how to can be found in the archives.

ahh ok so if thats not the problem then wat else could it be? im thinkin faulty injectors... but really dont know .. oh the info on my car is 88 t2 jspec bridge port

rexaholic

damn. good luck trying to fine tune this car. turbo cars that are anywhere higher than streetport are very hard to maintain a stable idle.

i just dont want it turn off feel me it could idle at 15 if it wants to but run soo rich and just die out i need help guys common .. the tps is fine and so is the bac valve so watelse can it be___ im getting 110 compression on both housings ... im really stuck now

tru im about to put a wideband on my car to see wat it looks like... ok so since i bought the new secondaries and im sending out da primaries to get cleaned and flow tested that should clear up my problem right__ if not then wat else could it be?? oh and another thing how can i checktif my turbo is leaking oil??

WTF?!

You are running a Bridge port, on an RTEK? What size injectors are you running? And you havent put a wideband on the thing to see if its hitting a bad cell?

wow...

bebiracer

i just rebuilt it dude and its not a full bridge its a weird bridge that some guy told me to try its called the swiss cheese port ... for people that dont know wat that is its basically a big streetport wit 4 1/16 holes on the side like a bridge its said to be much more reliable so i did it .. and im running the 720 secondaries and 550 primaries

You did a cheese port... Oh man, there has been alot of problems with that port. The holes cause turbulence that causes all kinds of odd problems. There is a reason its not used anymore.

Not trying to be mean or anything, I am just thinking that your setup and that RTEK arent providing you with appropriate AFRs once the car warms up and the BSFC starts changing. The only way you can tell is with a wideband.

Here is a pic of a Cheeseport for those that dont know:



And here is the thread that discusses it:

yes exactly the port i did ... so then why do u think it wouldnt give me the appropriate afrs??

If you read the thread I posted earlier, you would have noticed that almost everyone that tried this port had little or no luck getting it to idle.

Now, on to the RTEK and your AFR:

The RTEK is a wonderful tool, but it has its limitations. I dont think its capable enough to safely control that engine. Your idle AFRs are determined by several things, all of which appear to be marginally controllable by the RTEK. So if your car is not running after its warmed up, its possible its entering a cell that is running too rich to effectively idle that car. Its because the BSFC of the motor changes as it warms up, hence the reason for warm up compensations on standalone ECUs.

So, you either need to tune that RTEK, get a standalone, or accept the fact that you built an engine that nobody has any luck idling.

tru i think im gonna try to get it tuned or just sell it and wait for the megasquirt... thanx j-rat uve been a good help.. ok now one more question if im burning blue smoke mixed with the smell of gas... im premixing is that normal if im running rich like u said??? if not then could my turbo be leaking oil?

bebiracer

bump?

If your turbo is leaking oil, you can check your intake for oily residue. My guess is some oil is getting past the ports.

bebiracer

and how is that possible that oils is getting past the ports??
