turbs06 Member 42 Member For: 16y 3m 16d Gender: Male Location: Adelaide Posted 18/02/09 04:04 PM Share Posted 18/02/09 04:04 PM Had the car put on the dyno to test the Capa generic tunes to ensure all was running well. BF 6spd auto - Mods so far are Monza style FMI, K+N air filter + typhoon lower intake. The result I was given was not to run the Capa tunes due to the A/F ratio going to high. They did a power run stock and it made 232 rwkw. Loaded in the 8psi tune and made 279 rwkw. They would not run the car with the 10 psi boost level as they said it was not safe. When I looked at the dyno chart the A/F reading on 8psi looked to be in the high 12's, I didn't think this was too bad? I was advised that the A/F ratio should be 11 - 12? Any feed back on this.I now have the car booked in for a custom tune and upgraded fuel injectors. I am hoping for 300 rwkw. Link to comment Share on other sites More sharing options...

Mid 12's are just fine, particularly at lower boost levels (10PSI included).If that is what you had on your 8 PSI map then drive and enjoy.

The car was run with generic tunes, stock actuator and stock injectors - not alot of room for safety when giving it a boot full on a hot South Australian day. If the car is driven on a very cold night with an AFR like that, the car may overboost and lean right out.Pending the results of the custom tune I would say the tuner has been responsible with his customers car...Fark I sound like a boring old fart...

turbs06 Member 42 Member For: 16y 3m 16d Gender: Male Location: Adelaide Posted 20/02/09 04:38 PM Author Share Posted 20/02/09 04:38 PM The car has now been custom tuned with larger injectors. The A/F ratio now sits fraction over 12 all through the rev range on 10 psi and is making 306 rwkw. The power is very progressive and makes max power at 5200 rpm dropping off at around 6000rpm. So now it makes more power at lower revs and does it easy and safely. I was told that it made over 320 rwkw but was slightly detuned for reliability.

On stanadard tune with these mods the car made 232rwkw, so does a custom tune with injectors = another 70 rwkw? Attached is the Dyno printout? Any comments welcome.
