The car "spits" when the engine is cold. What is the problem?
I have some problem with my car. My tuner could not find the problem...
I hope all tuners out there can help me solve the problem. I will be happy!
I have:
MREV2
5/16 plenum spacer
DC Headers
Test pipes
Megan racing OE-RS exhaust
OEM 06 intake with K&N
UpRev Tuned!
I have the "spit" issue on a log..

Don't really know what you mean.
If I had to guess,sounds like what a older car with a choke would
do if the choke was not set right or,you let the choke in too early.
It would sputter a bit until it warms up.No codes showing?
As everything on the Z is electronic,I'd look in how the engine manages
the warm up function.

Yup! Str8dum, can't wait to see what the map looks like! lol OP, please if you can take a pic of your map and we'll see what we can suggest. As str8dum said, rich at idle. I don't know who your tuner is, but I suggest you get a PRO TUNE. It'll save you time and money.

Does that mean he cannot get the car adjusted to be RICH when
its cold?
You may not have an abundance of tuners in you country.At least that
understand the engine management system on a Z.
I'd get another opinion.Take it to another shop.

He is a UpRev PRO-Tuner from England. I have the Osiris UpRev standard, so my car is tuned through E-Tunes. We dont have a UpRev PRO-Tuner in Sweden. Is it hard to work with UpRev Tuner version? If my local tuner never have worked with UpRev..He has worked alot with Haltech and some others..
