i just realized that the ep82 launch control trick I did mention with special throttle value was not compatible with add and trim injection setup. So I would recomend not to use it.
thanks to nyahbingi who was having same prob and fount it out
will check out if there is any other way

this afects ep82 only.
when you want to use launch control. it will need to know when you are full throttle to activate. but ep82 ecu isn't connected to EMU throttle signal (at least greddy diamgrams doesn't tell where to connect it) so EMU won't know when you are full throttle. I jsut used a trick so EMU thinks you are always full throttle. which EMU injection side doesn't like when you use ADD/TRIM setup.
One way to solve this would be to send a 5 volts signal to EMU throttle wire when you are full throttle.
didn't have time to look around as we had more important things to work on. but will try to think and find a way if nobody has solved this before I got some spare time again

if you read well, I said it was still working even when throttle trick wasn't used anymore.
we previously found out that it won't work on some ramdom occasion, that's why we tried that trick and was happy as we were using add only on this car at first
note: this is related to ep82 ECU only

ok lads hear gos its not easy for me to put this in words lol
ok in the pix u will see the tps set up (make sure u have not wired in the tps wire ) if u look at (now) u will see a reading somthing like 0.10v its changes abit from time to time but not much if u tick both manua boxs and in put 0.00 in min and in max put a reading say 0.05 (might not be that amount just paly about with it will u get it) u will see as ur changing it the tps now % changing. u want it siting at about 55% this will let ur lc work with out the car trying to clear the plugs (it trys to do this at a tps reading over 80% i think) the 0.10v in the now box will change a small amount from time to time thats y u want it siting about 55% so u dont end up with the car trying to clear the plugs .pixs just to give u a idea of the boxs im talking about . if u need any more info just pm me its hard for me to put it in wordss as im crap with that sorta thing as im sure u know by now lol

what is everyones fuel cut set at on these ultimate's
i seem to hit fuel cut when i hit high boost in 5th gear only.... thinking it may b the fuel cut somehow....... it still runs fairly rich so i cant see it being a lean out but yeah... just odd to me

like it is left on 5 volts till about 4000 rpm then i reduce it to 4 volts and it still cuts at anything above 15psi
