Just had my car RR, will put the graph up in a bit but the most worrying thing is the AFR, now I believe the car is standard apart from an apexi induction kit and kakimoto cat back system.

 

The AFR was 10.2 from 4000 rpm onwards :eek:

boost was a solid 9psi.

 

What the hell could cause that fueling or is that safety overfueling.

 

will be pulling the ecu tomorrow to see if it has been chipped, as the operator said the car seemed fine and just to up the boost to sort the overfueling. :slap:

i fecking hate that approach ( up the boost to sort out the overfuelling), find out why its overfuelling before doing that bud.

thats my opinion too, I want the car right first before fiddling with it.

The standard chip is set to run the engine in the 10s under WOT it's built in safety. Unless you know what you are doing and can monitor your own AFR leave it rich.

atr point my car was running way rich than 10 as it went off the scale that the RR records to, I don't like cars running excessively rich like this.

 

If what you are say is correct then I will be looking at getting the car chipped and set up to run better

Sounds like the correct fuelling to me....

oem chips tend to overfuel slightly for added protection so as andy says sounds fine to me :) good results for a filter and zorst

okay so this is just the standard ecu being safe with the fueling. Okay so I will get my new HKS exhaust fitted and then check the AFR and re-map if needed to take a boost increase
