Re: 4l60 no 4th gear

Thanks for that Chuff. Luckily in a way , most of the hydraulic items are much less likely now due to the currently not active fault ! Electrically much more so likely . I looked over the log data again last night and I have a pretty strong feeling that there is a wiring/connection issue possibly at...

Re: 4l60 no 4th gear

Ok so , Looked at drive log data from yesterday. All seems mostly good as far as tps , speed sensor , etc. There was a discrepancy though between the tps engine data and trans tps at the same point , namely full throttle of one instance anyway. The eng data says 4.86 volts and 99.61 throttle % but t...

Re: Cold and hot idle setting strategy ?

The part I wasn't sure of was if the same rpm in the closed throttle VE should match the main VE . I probably should untick the...

Re: Cold and hot idle setting strategy ?

I have been using the idle ve table in closed loop but I only initially adjusted the few cells and slight adjustments to the matching afr , mostly I was trying to lean it off a bit for warm up cycle .
