off topic abit... now pulak i start to encounter e manage ultimate limitation . if you would allow me to share what i had encounter.
1) is the famous rev cut limiter setting. its not too stable. meaning to say after all the so called clamp at certain rpm and then input injector duty cycle and hold for certain ms. this thing isnt consistant... i get my "set" rpm on 1st and 2nd gear but not on my 3rd gear. sometimes i get... sometimes i dont...
2)map resolution 16 x 16..... not enough in all aspect.example... load vs rpm. 500rpm increment each time... 16 box means up to 8000rpm... sure can re-scale and it wont be fine anymore. so have to pick a point. since its a piggy back .. stock ecu is sufficient to play the front off boost drivability wise. so the scale can jump every 1000rpm. till around 3500 where start seeing boost then can do 500 increment so that i will have more rpm to tune at the back... same goes to load. even wid a 3 bar map sensor. i have to rescale my vacum to only use 3 box and the rest boost.. scaled up to 2 bar... front low boost can scale further abit.. but the critical part really need some finer resolution. maybe im not too good to tune. so not sure if thers any xtra trick to tune.
3) ignition timing not consistant... tis is bad... on my top end. somewhere near 7000rpm, my torque start falling , since its after peak torque , i raised up timing till i detect knock and back off. thats around 25 degree. no knock, low compression, 1.8bar of boost... but when i datalog it.. at some time the timing can go till 26 and ngam ngam 26 knock will happen and the stock ecu pulled back heaps of timing to eliminate knock causing drastic drop in power... no wonder sometimes felt the car isnt pulling right wid my butt dyno.. datalog it and seen tis happen.
will soon give a try on microtech lt16.. see how it goes... just damm
scare i cant get the damm car start and drive right in the first place.
