Question 1

Question:

I’m no car expert. Would this make my 1991 Z faster and or more responsive? Are they difficult to install? Is there anything else you sell that is somewhat of an easy upgrade for performance? - Michael

Answer:

Hi Michael, these mostly benefit the TT as they allow you to run higher flow-rate injectors and different intake configurations. They do optimize things a bit for the NA, but there just isn't as much to change on the NA. If the ECU is stock, these require pretty high soldering skills to install. Otherwise, check out our full ECU upgrades as those are the same thing, just with having us install them for you.

Question 2

Question:

If my car is a 1994 NA but has a 1992 ECU what year should I put down? - Max Kilbourne

Answer:

Hey Max, you'll want to go off the ECU's year, so select 1992.

Question 3

Question:

My car is an auto to manual conversion and still runs the auto ECU. Should I select auto or manual in the options list? - Justin

Answer:

Hey Justin, select for Manual

Question 4

Question:

Hi I'm planning on doing the na to tt swap. I see you guy have an option for that. Now is that for putting the turbos on the na motor. Bevause that what I'm doing . Running the high compression motor. And if so can I use this eprom chip for the tuning of the car. - James connor

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.

Question 5

Question:

what is the maximum boost pressure you can run with this chip - ken

Answer:

We normally recommend 14psi on 91 octane, or 16psi on 93 octane.

Question 6

Question:

Can these drop into JWT socketed ECU's as well? - Billy

Answer:

Hey Billy, yes they can

Question 7

Question:

Hi I'm interested in getting one of these chips but I was wondering if I have a single maf set up now and got the chip, would I need a new chip if I upgraded to the dual maf setup or would the chip be able to adjust? - Cody

Answer:

Hey Cody, you'll definitely want to get it for single intake now, and when you do dual intake, as long as you get the Selin translator, you can use it without changing the chip. You'd just need to run the Selin translator in Add mode.

Question 8

Question:

For a dual intake setup, will the ecu need to read two MAF sensors ? - Scott

Answer:

You can run a single MAF + a dummy MAF but you'll want to run a "low speed driveability" hose like the old JWT dual intake kits did back in the day. The preferable way to do a dual intake is with the Selin Translator, which does indeed read two MAFs in parallel.

Question 9

Question:

Does this chip upgrade eliminate the AIVs? - Kevin

Answer:

Hey Kevin, they do turn off the AIV solenoid flag by default. We can keep it on at your request if you prefer.

Question 10

Question:

Will the chip automatically adjust my ignition timing if my car was previously set for 93oct but I’m now on the west coast where only 91 is available? Also, I see there’s no longer an option if I have boost jets or not. Will that be an issue/matter? - Erik

Answer:

Hey Erik, basically you'll want to select whatever octane fuel you currently run. As it replaces any previous chips, it won't matter what you had set up in the past. And it is compatible with boost jets; those are simply one way of raising the boost.

Question 11

Question:

Needing to order an eprom for a Z32 I'm working on. When selecting the year, do I select the year of the car or the year of the ecu? Also, does it come with a sticker or label for the outside of the ecu? Doesn't really matter, just curious.

Answer:

Hey there, you'll want to select the year of your ECU. The chip itself will have a printed label with the options selected, as well as your Order #, for easy look-up in the future, but does not have a sticker to go on the outside of the ECU.
