Hi guys!
I have recently fitted nismo 740 injectors in my SR20. I was out today for the first time, cruising with o2 feedback turned off. I adjusted K from 16550 to 15500. This gave a good stoich at cruise and made the car feel a bit better generally. It still idles like crap but I'll have to look at that later.
Anyway, my question is:
A) what is the Clear Self Learn function under Active Tests please? I read that I should have Clear Self Learn running while making adjustments, why is this? I can not find anything about it in the manuals.
B) the car is now bucking like a mule at low speed/low loads. Its hard to drive through a slow village without it constantly bucking. I have read that this is due to having too little advance. The strange thing is that I have not touched the ignition at all, all I have changed recently is injectors and fueling. Any dea why this might be happening?
Many thanks!

Re: Clear Self Learn & Car Bucking While At Low Load
Clear self learn will erase the long and short term trim values stored in vehicle battery backed memory in the ECU.
Trimming against current injection is shown in consult adjust the AF Alpha (short term) /AF Alpha learn (long term) gauges as a percentage over/under stoich
Bucking can happen if the AFRs are out and its running too lean also. What are the AFRs like on the wideband during low throttle situations (with / without O2 sensor feedback enabled)
