This product is reprogramming an existing Velosyty chip. You would need to send in your existing chip.
Available now for stock injectors, 40lb Redstripe, 42lb disc-style, 50lb MSD/Delphi and 60lb injectors.
Typically takes 7-10 days to make the chip, so plan ahead!
If you don't own a scantool, then this chip is not for you. If you are expecting to improve and refine the performance of your car, you need a way to confirm sensor readings and troubleshoot. I cannot help you with troubleshooting without any data. A good portable scantool is the Scanmaster 3, sold in this webstore, but something like Tunerpro or Datamaster work well too.
A completely new program for the Syclone/Typhoon! Many improvements to the chip programming to improve cold starts, idle, response, and general driveability. Can be programmed for the stock 2-bar MAP (stock injectors only) or a 3-bar MAP, although a 3-bar MAP is recommended for better boost control. Also includes the ability to read a wideband O2 system (connected to the ECM), and makes corrections at full throttle (above 10psi boost).
The chip is mounted on a memcal adapter. You remove your old memcal and plug it into the new adapter, then plug the adapter back into your ECM. (You need an old stock-type memcal for it to work. The programming on the old memcal doesn't matter, as long as it was originally made for a Syclone/Typhoon.)
Optional secondary program can be put on the same chip ($55). It is selected by a small switch on the memcal adapter.
Knock Alert, flashes the check engine light if knock retard exceeds 5 degrees
Compatible with "EGR delete"
Also includes user adjustable features.
There are 2 rotary dials for basic idle and WOT fuel control, and 3 on/off switches for some other optional features, like open loop mode, open loop idle, and wideband/narrowband simulation mode. (Currently, a 2-Bar chip does not have these dials and switches, but does have the user adjustable parameters below.)
There are other internal user features, these are adjusted using a procedure with the throttle and watching some numbers on a scantool.
User adjustable features are:
1. High boost fuel
2. Mid boost fuel
3. Low gear timing
4. High gear timing
5. Initial wastegate duty cycle
6. Target boost
7. Closed loop WOT A/F target (requires a wideband system connected to the ECM)
