im moving this thread to Fi since the problem has happend since i installed my injectors and my vortech supercharger. i got dw 600s and my vortech supercharger installed and its been fine starting up but only when its ran hard and now that its hot outside it gives me problems when i start the car itll crank and just not start. than ill chill for a few seconds and it starts. is this just a problem with bigger injectors?

 

Utec?

 

no osiris uprev

 

A lot of people have this problem. Go to your tuner and ask them to fix it. Uprev fixed it with no problem.

 

yeah should be all in the tuner... a lot of people even complain about utec and hot starts.. i never had a single problem with it.

 

Here you go. Look at post 7

Hope it helps. I have the same issue an I working on getting it fixed.

 

yeah il be back at rt tuning in a few weeks for a pmas maf and retune anyways.. it only happens when i run it hard and its hot though. so he can fix this in the tuning?

 

rt tuning.. with vince right?.. he should be able too... I was going there to him to tune my setup.. i would hope he can.. I wouldnt want to drive another 3 hrs to fix it

 

yyeah im sure he can... hes tuned my car when i was na as well.. and the car always feels perfect . he always has made me happy with him tuning

 

Just had my Z tuned there last week. APS TT with UpRev and I have 0 problems with hot starts.

 

what injectors? and what part of jersey are you in

 

DW 600cc with Walbro 255. Central NJ Exit 117 of GSP

 

yeah im central jersey also off of exit 105.. i also have the dw600s and the walbro 255...

 

I have heard about your Z haha. Few people asking me about it. I keep telling them I have no idea. Gotta meet up sometime, I know no one around here who mods a Z / G

 

Hey Joey, its prob just a slight adjustment in the start fueling...we tuned that thing in FEB(or sometime cold) if i recall. When we get ya in for the PMAS MAF we will trim it in for ya in the hot weather and you will be set. Those 600cc and higher injectors with the stock fuel system configuration are tricky for hot restart...they need to be pretty close to perfect...

 

My co-worker is off that Aberdeen exit too...you can usually find me over there drinking and swimming on a friday afternoon in the summer while "home office-ing"

 

Should be an easy fix, just need to tweak the startup enrichment table in the warmer coolant temp cells.

 

Well then, have to def get some Zs / Gs in the local area and meet up one night.
