Answer:

Hi James, the option on this chip is for swapping a TT motor into an NA chassis. Unfortunately we do not have a chip that will support a boosted NA motor.

Got a chip for my 91 NA Z. Right off the bat I could tell a difference in how it ran. Throttle is more responsive, low end pick up is much better, power band through entire RPM range is much smoother. I thought my Z ran good before the chip, but that was just the cherry on top. GG, would recommend!

Very impressive how such a little tweak can make such big changes. The car ran smooth already before the chip, but especially the throttle response got so much better. Runs like new.

First off, it is an absolute pleasure to work with CZP for so many reasons. Anyways, my Z was not passing CA smog, and this tune (along with some new plugs), and the car passed with FLYING colors. Not to mention the amazing throttle response, and overall improvement of the car running. Butt dyno felt a difference too! Absolutely best money I have spent in awhile!

Description

These are the same EPROMs we include with our full ECU upgrades. If your ECU has already been upgraded or modified in the past and is already socketed, these can easily be installed by just swapping out the chip.

Features & changes to the program, compared to stock, include:



-Street Legal (90-94)
-No Adjustments needed
-Rev. Limiter Raised to 7200 RPM
-VTC Release point optimized
-Eliminates Top Speed Limiter and Boost Limiter at ECU level
-Throttle Response Code Optimized
-Fuel/Timing Maps rescaled to allow higher boost pressure
-Air/Fuel Ratios corrected for higher power levels
-Ignition Timing corrected for optimum torque
-Computer Controlled safety boost level maintained


Please note: If your ECU is stock, you will need to have it professionally socketed before you can install one of our EPROMs. We offer an option above to include the physical socket, but you will still need to have the stock EPROM chip desoldered and removed before the socket can be installed. Our Full ECU Upgrades take care of this step for you, allowing you to send in your ECU for us to socket + chip.
