Had a fmic fitted along with 850cc injectors plus fuel pressure regulator on my 2002 bugeye, fuel and air mixture isn't right so I thought of getting a standard map just so it runs right till I have my Syvecs Ecu fitted and remapped properly things is its reading too many fault codes and every time we delete the codes they keep coming back up.. here's the list of faults after diagnostic was done.

P0303- cylinder 3 misfire detected
P0304- cylinder 4 misfire detected
P1234- multiple cylinder misfire detected
P0304- camshaft position sensor circuit malfunction
P0102- mass air flow sensor circuit low input
P0500- vehicle speed sensor malfunction
P1507- idle control system malfunction
P0172- air/fuel adaption, back 1; rich mixture
P0301- cylinder 1 misfire detected
P0302- " " 2 misfire detected
P0303- " " 3 misfire detected
P0304- " " 4 misfire detected
P1235- multiple cylinder misfire detected
P0113- intake air temperature circuit high input

Would appreciate any feedback on resolving the above issues..

 

The cam position sensor maybe causing all they missfire codes, id change it and clear them again. Sounds like the maf has failed too also causing the afr fault code so the maf maybe causing a few codes to pop up.

 

Thanks for your input Jay, will try that out mate.

 

Are you using Romraider ?
Only you would be able to see if the MAF is any good thru that.

 

More obviously the issue is you have fitted 800cc injectors etc on a standard ecu with a standard map...

Of course it's throwing codes!

 

I would agree with this, the mixture will be so rich it will hardly idle at all and as soon as you go to drive you'll be spitting raw fuel out the back.

 

I fitted PE800cc to my Blobeye Sti along with bigger turbo, headers, uppipe etc and i got a code saying system lean , although it didn't appear for most the drive to Andy F. 40 miles away

Agree with the idle being crap mine wouldn't stay running as i came to a stop it would die on me and id have to fire it up again

 

JDM stig no mate.

JGlanzaV yes your right but was about to have someone map the car for me but he didn't go ahead with mapping as he couldn't delete the codes as they kept coming back up, so what you think next step should be??

 

the misfire codes you can't delete you can only clear them - the low voltage on the intake temp sensor and MAF could also mean the MAF isn't giving a good reading (inlet temp sensor is in the MAF). I assume the guy who was going to map it checked the MAF readings to see if they were sensible or crazy - could there be an earth point off anywhere that's messing with the sensor readings?

 

Cheers mate.. did read elsewhere aswell that codes can't be deleted only cleared, and defo no earth point off anywhere but I'll add that to my check list again and look over it ��
