Which 'load' is used in the PC calculations?

Lance,

As title, which 'load' variable is used in the Pressure Control table? raw MAP load from the Canbus or the load after blending TPS with MAP?

Re: Trigger hysteresis using avload instead of load?

Lance, I reckon I'm pretty much there. I'm even considering screwing the lid on the MSGPIO and tucking it away out of sight as I don't need access to it any more. :) I'm using the car almost daily now and the transmission is now very OEM like. I think I mentioned somewhere else, but on the 4th May I...

Re: Trigger hysteresis using avload instead of load?

Funnily enough I was running the load hystersis at between 30-50kpa to effectively disable it with the previous code.. I WAS running the TPS/Load at 90% and then experimented with reducing it, the performance improved each time. I settled at 50%.. maybe I'll try going a little lower. I've found that...

Re: Trigger hysteresis using avload instead of load?

I've put a few hours on it today, it still occasionally mishifts, but it definatly needs more tuning now. I also sometimes get slip in fourth, but I'm working on the theory that its because I sometimes find myself in fourth in low rpm/load areas so the line pressure is too low.. again tuning should ...

Re: Trigger hysteresis using avload instead of load?

Hello Lance, Its taken me a while to get the chance to drive the car with the new code.. I have the TPS table as you suggested above ^^^ I've left all the new code options as default. Just been out for initial drive and... well... its about OEM as I could get. I mean its really really good, drove pe...

Re: Trigger hysteresis using avload instead of load?

Honestly, after hours of studying datalogs etc.. I do think your code is working correctly, I think its just down to tuning and getting more hours in the seat. Getting the relationship between load, TPS, TPS loading and speed is more critical than I imagined. Studying the datalogs I took of the fact...

Re: Trigger hysteresis using avload instead of load?

Maybe 50% is too much at the moment for a cruise/daily car. Probably more suited to a more sporty drive. For me the addition of throttle makes it more likely to downshift with an increase in throttle, it all comes down to tuning for each application. I need to spend more time with it.. I can't say t...

Re: Trigger hysteresis using avload instead of load?

Lance, it was 20kpa without doubt.

I've just been out for another run, the only thing changed is that 20kpa up to 60kpa, but more importantly the load/tps slider was set to 50%

The load traces look far better, but the driving experience was worse..

Re: Trigger hysteresis using avload instead of load?

Sorry Lance, didn't work..

load and avload look very odd in the datalog, the 3-4-3 shift still occurs... I've attached my tune file too just in case..

Re: Trigger hysteresis using avload instead of load?

It occurred when I loaded the latest INI into my Tuner Studio project properties. I thought I'd better raise it with you first.. I'll continue then..
