Hi all,

I have a couple questions for the Z pundits out there. Two q`s:

1. I`ve steadily modded my Z away from stock. Nothing unusual or gravity-altering, but things are starting to accumulate. I have the following breathing mods on the car now:

A. Jwt popcharger
B. 5/16`` Motordyne spacer
C. JIC 3.1`` single y-pipe back.

These changes, along with some dedicated weight-removal and a UR 15 flywheel have changed the character of the car - sharper, more high-rpm, pull, etc.

Q: Do you think these 3 mods would warrant looking into some sort of tune? If so, what is an economical means of doing this? I think I`m out of the UTEC budget btw.

Q: Unrelated to the previous q: Mine has always done this. Do your Z`s drive very sluggishly while the motor is cold? I baby the car for several mins., before starting to give it serious throttle (ie. more than 3.5k rpms and/or 2/3 throttle), but the lack of throttle response and general low power within the first 5 mins of start up always draw my attention. Do these cars pull lots of timing / run rich while cold as a protective measure? If I had to, I doubt I could beat a civic while running cold.

Thanks!

 

You don't NEED a tune for those items. If your budget works, you can do the UTEC. If not, it's no big deal. You could always get a flash.

 

the question is...are you done modding? If so, then tune for more power, however, if you plan on HFC or TP (either are a must imo), headers, exhaust, or the like, dont tune yet.

 

my car always feels 'off' when it's cold...but as soon as it warms up, the engine feels great. Not sure why that is - maybe the ECU has some kind of setting for cold engine temps.

 

I know of Technosquare - mail the ECU, ~$500, etc.

Anyone have opinions of shops to visit in the Midwest (near Chicago or north of there)?

Thanks again!

 

Look into UpRev mail in reflash as well!

 

I would personally take that 500 and invest in a utec.

 

Sound Performance and GRD (genesis racing development)

I am going to Sound performance soon to have my utec tuner installed along with a few more mods

 

ok, a tune or tunable piggy back would be my first item on a car if i was modding it, for instance, had a bone stock G35 come in, it put down 239 on my dynojet, i put a KnN in there and a UTEC to control his 100 shot.

i was able to get 255 out of the car with almost 17 hp in a few spots, only mod was a UTEC.


i would add a piggyback computer to the list of the first mods to do, then i would get a deal with the dyno operator/tuner so when you change any mods, he will retune it for a special price.
