Hi
Iv'e been maffless tuning my VF commodore and seems to go very well
so far but when you start using wot then cruise at say 1500-2000 it gets a hesitation
after a wot run but only then.
Apart from that it drives really good.
Anyone had this problem any ideas what the cause is?
What's the ramp rate for PE and enrichment, in and out?
PE ramp in 1.10 ramp out 0.01
PE delay 2000 rpm
Whats the AFR during the problem area?
Need to find the log but I remember afr is fine then goes lean when it happens.
The cars hesitates/ jolts then its fine.
Post files.
Actually looks to be timing dropping.
In the pic it drops to -3 deg.
