Hello,

I am just getting the car running and im having a few problems ill list separately below with a couple attachments of logs. This is a 2jzgte with a single turbo aftermarket intake currently on e85 with 1600cc injectors (bosch). I have a feeling there maybe something wrong with the cam or crank sensor maybe, im not sure.

1st issue, only during cranking it likes to flood the engine. I have rather large injectors and i believe that the cranking pulse width is too large causing the motor to flood. I currently let the car prime a bit, then pull the relay for the fuel pump, start the engine and plug the relay back in before it runs out of fuel in the rail. and then itll idle fine.

2ND issue, Under very low movement of the tps it acts up terribly, but if i throttle if kind of fast itll rev up but that will usually end in a backfire and the engine turning off. usually once it backfires i cant throttle it to stay alive and it falls on its face. (See Log)

Thank you!

This is the log, if it allows me to upload. It keeps saying "Sorry, the board attachment quota has been reached."

so just incase anyone is having a simular problem i will go over a bit of the things that were wrong with my tune.

First i realized the idle air control was set to sparc cut above 1000 RPM which was no good.

second i went through my logs for ignition and realized that i had my camsync trigger tooth going from one constant value to another randomly. I was able to fix my issue by disabling camsync above xxxx RPM which i set to 1000 RPM. I believe the same thing can be fixed by using the camsync advance filter and inputting the correct values for trigger tooth and tooth deviation.

Good luck if youre having the same symptoms!

if your camsync is shifting to a different tooth as the rpm rises then i would suggest you might have the wrong edge selection for the cam sync.
