CCCI fuse

[Steve Wood]

at the moment, I don't see a big problem...look s like the wot fuel needs to be adjusted downward to me...what were the factory o2s?

How much boost was the chip burned for? 

[larrym]

I adjusted the fuel pressure and brought the boost up 20psi a bit so far so good.
Block learns and 02 readings seem good now I will continue to play around with things and keep you posted.


The chip was burnt for 25 PSI I'll bring it back to that slowly.

[Steve Wood]

so then you would expect it to be rich at lower boost

[larrym]

now for the next issue when I get on I get some knock initially that clears up and my as fuel seems to catch up to he boost.
dirty injectors?
failing TPS?

[Steve Wood]

too much alky for the amount of boost that the car is seeing at the moment, or it is hearing another noise such as the dp banging the control arm ear, etc.  At times, it can be the opposite and too much boost for the amount for the alky being sprayed.

Sometimes hard to discern between rich knock, transition knock, and false knock.

It is hard to program alky for relatively low amounts of fuel....

Pretty sure it is not injectors or tps

[larrym]

its audible could that still be rich knock?

[Steve Wood]

rich or transitional.. .what does it look like on your scan tool?

[larrym]

its just when I first get into it doesn't last long hard to watch the scan tool and everything else at the same time I'll wrangle my buddy into giving me a hand to track the ECM 02s and the knock retard on my scan tool. I can record but its slow and I might miss the event.

[Steve Wood]

If you have a lot of alky spraying early and the boost does not come up fast, you can get an audible knock for a split second

really need to see some numbers and try to see a pattern.  That is why Powerlogger is so nice...you can see in between the normal frames
