I noticed in your Sig you were going with ID1000's and E85, same as I have. If you have already made the switch and the weather is getting cold then this is your issue. Cold weather on E85 will cause rough starts.

Not calling BS as I have no clue. What's the theory to that?

Google E85 starting in winter. Theres lots of info on it.

This is also why they change the "winter" blend from E85/E90 to E70. To help with cold weather starting.

I still currently have 600cc injectors and 93 octane tune. My old tuner has been MIA for over a month now or I would have already make the switch to my 1000cc's and e. I do have the GTR plugs and a few people have told me that could be the issue. Sebastian is pretty sure he can get me lined out. This problem has been happening for over 2 months now even back when the temperature was in the 70's. Every once and awhile the cold start even throws a misfire CEL.

Yeah there is no doubt it is much harder starting on E in cold weather. Have about 5-10 people around here that have that problem.

Well that didn't change anything.

When you took the water cooler out of the intake manifold, you just cut a square in the front, pulled it out, and patched the hole? Are you positive there isn't an obstruction inside there that's blocking one of the throttle bodies from flowing?

I would reconnect the front of the intake pipes to the supercharger, and then disconnect the intakes from the throttle bodies. With the supercharger blowing, you should see some voltage on the mafs. If they're still unbalanced, your problem is in the intake pipes or MAFs. If they are balanced, then it's an obstruction in the throttle bodies or intake manifold. At least it would give you a direction for where to look.

We had it off several times, it is completely hollow with no obstructions. We will try your idea to test the pipes, I hadn't thought about that.

I just keep thinking this is not a mechanical issue. It sounds electrical. Some sort of wire is not either connected correctly, loosly connected, or not connected at all.

I almost want to fly down there and take a look. I mean, its 15* here right now! That Florida weather would be worth the trip.

JWillis72 · 12-18-2015, 10:20 AM

15, that sucks man. If we don't get this figured out soon I might have to buy you a ticket! I'm going there in a few hours so I will go over the wires again.

I too am running the GTR plugs, cold start issue is all in the tune! Last time my Z was tuned the tuner asked to keep the car over night so he could have a go with the COLD start up adjustments to prevent the misfire CEL. I have never once had an issue again.

My car always fires right up however my dads GT-R has a little more trouble. (Both cars were tuned by Seb at specialty Z)

JWillis72 · 12-18-2015, 01:08 PM

Checked all the wires again including the VVEL and everything is connected. It's dumping rain and the doors are closed so I couldn't try the resets myself, maybe Monday I can get up there

Exactly what I figured because it started up normal with no problems until about the 4th flash. He changed something but told me there was nothing else he could do. Literally was on the 13th flash trying to fix it and haven't heard from him in over a month now. Such garbage. On to Sebastian!
