Had my car down at Thor this week, just to see if it was running well, thanks guys. The results showed that its overfueling.

 

The car is pretty stock, Mongoose cat back exhaust, and blitz dump valves on hard pipes. It will have a blitz induction kit on it tomorrow.

 

What options do I have?

 

can this be fixed without upgrades?

Suggestion of upping the boost to use the extra fuel, either by mig tips, boost controller and a fuel computer (emanage, apexi)

 

 

Looking into finances, any upgrades may have to wait till next year

 

 

Thanks in advance.

Worth checking for boost leaks first incase that's why it's running rich. What boost did Thor's trace show you were at.

Heres some figures, psi 0.62, at 70mph, 6155rpm. Other chart 233.4 Hp DIN, 73mph, 6406rpm. Also 221.7ft/lb, 51mph, 4507. With the calculation this put it at 280BHp at wheels. Also its a UK car and Auto. Guessing these figures are pretty standard!

 

Looking at the PSI graph, it starts about 0.58 at 2400rpm, drops alittle, then slowly rises to 0.6 at 4500rpm and carries climing to 0.62

top tip.. put less fuel in ;)

Put a sock in one of the injectors?

Sorry, that's not very helpful.

What chip is in it? How much is it overfuelling, whats the AFR like?

Worth pulling the vac line off the pressure reg with engine off, see if it hisses, if it does then the PRVR system might be stuck, putting too much pressure on the reg. Dodgy fuel temp sensor will also activate the PRVR Definately worth checking the fuel pressure anyway.

Are the lambda sensors OK? If one is showing lean all the time then the ECU will add more correction and enrich the fuel. If temp sensor is faulty can also cause it.

Best place to start is get it on a consult first and see if everything is OK.

Thanks John, most of that went over my head. The car isnt chipped, everything is standard. The car went on Consult late last year and didnt show any problems at all. Might have to wait till I can get it to Phil at C & S wood.

 

Think I will have to use Scoops, or Craigs advice, thats more in my technical ability.

 

Thanks

No problem, hope you get it sorted.
