car will not restart hot, after running, not overheating.
at world cup finals, this issue really reared its ugly head. last year it cropped up at e town. cost me the furst round at the fall nationals.
when im in the lanes, and there is a breakage, i cant turn the car off, as i know it wont restart. BUT, with 2+2 it will start and run.
well this weekend, i had an issue, and thought it was lack of battery voltage. we put the jump box on the car it fired. made the pass.
next round same deal. breakage, had to turn car off, this time the jump box had no effect. so an idea popped into my head to pinch off the return line as i know the car never floods, it is lack of fuel. pinching the return line allowed the car to light up and run.
the setup is as follows,
83mm gsr maz cams
8.8:1
t3t67ho
rc 1200's with an oe resistor box
weldon db2015a on a dedicated switch so cranking fuel pressure isnt an issue.
msd 6al and blaster ss, plugs gapped at 18thou.
i am pretty convinced that i need a warm start fuel enrichment, problem is, im not a tuner. i can make changes, but dont feel comfortable making changes i dont know about.
so if the cal agrees what what i am saying, please direct me as to where to add fuel. and what incriments. thankyou.
i will enclose the last cal i used.
thanks guys.
sorry for the edit i had dislexia......1200 injectors.

i have the race logs, i dont have any cranking logs. can you even get cranking logs? (i am truly asking) i didnt know you could log the engine cranking.
idling isnt an issue. it is litterally just getting it to start. once it is running it is fine and i can go make the pass like nothing else happened.

over the last day or 2 have just learned about the cranking fuel trim.
i have a busted tranny from world cup, so when i go to fix that ill address that issue as well.
again thankyou all for the help.
i honestly did not know about the cranking fuel trim, my tuner had gotten back to me also, and said the same thing.
although he had said that k and flash pro have a temp / trim table. that the s300 doesnt. an addition to a later version? haha.

Mikey,
I really think alot of your hot starting issues are directly related to those injectors that you are using. I thought about it more and more and I have never needed a cranking trim vs coolant map with s300 before. Even on 1600cc's with no driver box the cars start under cold or hot conditions just like stock.
