Hello all, since I've had my ecu chipped, ( p28 in a d16y8) I've always had this problem when after I would drive around for a while, park the car for about 30min to an hour, then when i would go to start it, it would take a while for it to start.

Now its turboed and doing the same thing, when its cold it starts up fine, when its fully warmed up it starts fine, its just that "magic time" between when its cold and hot.

I know someone else has had this probelm, any recomendations. I've played around with the ect correction numbers in crome but i've had no success.

if someone wants to see my bin i'll be glad to send it to them.

 

play with the cranking fuel values.

 

thanks I'll give it a whirl tonight

 

Good luck man

 

I have the exact same problem with my b16 turbo. Its also tuned with crome. Mine started only after i put the turbo on. Its exactly like you said, when its cold it starts up fine, when its fully warmed up it starts fine, its just that "magic time" between when its cold and hot.If you guys figure it out please let me know.

 

all you gotta do is simply like I said adjust the cranking fuel corrections. You can also adjust for cranking fuel at different intake temps with crome.

 

I tried tonight but with no luck
After i finally got it started the datalog read the coolant temp being about 115 degrees

I lowered the cranking value around that area thinking it would help but it got worse. Are those values based off of stock 240cc injectors?

 

Well did u increase the crank, then play with post also and are u using larger inj. which may require less or more depending on ur map. Crank applies fuel only to crank the motor over and post applies fuel after the cranking of the motor depending on the amount of fuel for about 10 to 20 sec. until the inj. get to where they need to be to keep the motor running. Make sure ur map is not to lean in ur idle area cause this can also have an major effect after its threw its crank and post stage.

 

yeah I am using 550cc injectors, and no I didn't adjust the post fuel, thanks for the heads up

There isn't any formula to follow right, just trial and error

 

yes just trial and error

 

damn i thought it was going to be easy lol

Well since i have bigger injectors then the duration should have to be long since they are spitting out more fuel when open then stock right?

 

U will figure it out, just take ur time and play with those settings and always make note of what u have done.
