Need a little help PLZ
 

i recently bought a TII the engine was blown so i had it rebuilt and mildly ported. I also at the time installed a LT8S. i have 2 problems now @ idle no matter what map i change i cannot get get the sT ms below 3.0 ? has anyone had this problem before? also the car will cold start fine but after i turn it off @90c it will not start unless i put a battery charger on it. on hot start it doest matter if i richin it or lean it out it wont start untill i boost the battery.........

Any help would be great ,
Thanks....Ryan

the sT ms is dependent on various maps, not just the idle map. check all of your maps.

Ive tried most maps
 

ive tried changing the IDLE , LOAD, Water temp , and OPtrim and none effects the duty cycle...i dont know why?

mix trim? opt% stg?

?
 

isnt optrim and mixtrim the same setting? also if i change the stage% wont that just cause other problems?

no i dont think so, and I didnt mean optrim, i meant optstg%. it probably will cause more problems, it probably could fix it..... who knows?

By using the "Mixtrm" (screen 30) you should be able to reduce (or increase) the amount of gasoline, thus bringing it dow to almost "0". My car is happy iddleing with a total of 2.47. To start it (crank) it likes close to 7.0.

By the way.... the 7.0 is on a cold day on initial crank.

open loop?
 

i dont have an 02 sensor hooked up does the microtech have to have the 02 sensor.. does the microtech run open or closed loop ? also do you have the stock tps sensors or do you have the normal stlye tps

No the o2 is not required and the lt8 doesn't have a closed/open looped feature. Clarify the tps question please. I'm been running the stock s5 tps without a glitch for 3 years.

not really a problem
 

im just used to an full range with the right degree of throttle..
