overkill pcm question

hello, i tried emailing Will yesterday and havent gotten a response, i thought maybe i could get a quicker response here....
i was mainly wondering if overkill pcms came with the option of removing the 108mph speed limiter?
 


yes. along with alot of other features...(taken from his site)

Fuel control tuning
Proprietarily fueling individual cylinders, controlling burst KR from quick throttle inputs, reducing KR during extended full throttle runs, and programming the engine to run at an optimal air/fuel ratio.
Spark control tuning
Increasing the PCM's response time to hazardous knock, reducing spark retard quicker after it is no longer needed, decreasing timing in high load/low rpm zones for safety, increasing timing for better fuel mileage at part throttle and increasing timing advance to the high 20s-low 30s at full throttle for maximum performance.
Fan control tuning
turns on the engine cooling fans for 180 thermostat settings, runs the fans at low speeds in slow city driving for better cooling, allows 3 minute fan operation at high coolant temperatures after the key is turned off
Transmission shift remapping
increases the shift firmness and time without adding harshness, allows the transmission to downshift to a lower gear more easily when required, allows redline up-shifts at full throttle in performance shift mode, greatly reduces the bogging around town and on the highway at light throttle, extends the life of your transmission!
Abuse modes refined
disabling injector turn-offs which cuts fuel to random cylinders and revising dangerously lean air fuel ratios that aim to reduce engine power, that could be hazardous. Torque management is retained for transmission upshifts, to reduce engine power and allow the transmission to shift more easily and more quickly.
DTCs are selectively disabled
codes that pertain to the rear O2 sensor that can be set with use of an aftermarket high flowing catalytic converter, codes that pertain to the installation of a lower than factory temperature thermostat, codes that pertain to the EGR system for optional disabling.
Proprietary revisions
to enhance its interaction with popular upgrades and daily driving characteristics, such as raised idle for better cooling, alternator charging and power steering operation, quicker warmups when starting from cold, and smoother idle with poly motor mounts. Air conditioning is disabled under heavier throttle, regaining power that is lost turning the compressor and extending the life of the compressor itself. There are many refinements to the coding, to enhance shift quality, improve fueling controls, things that are not even begun to be touched upon in other PCMs.
A booklet with your PCM purchase which contains information about the PCM, answers more frequently asked questions about our PCM tuning, and gives tips on future modifications and suggested maintenance. Finally, your PCM is not an off-the-shelf tune, ever! We have tuned hundreds of different vehicle calibrations, and understand what is required to make the best calibration for different modifications. Each custom calibration is done as part of the standard pricing, you won't pay extra for simple changes, simply provide us with a modification list and you will be shipped a custom calibration based on the anticipated needs of your unique setup.
 
Hello,great description of your product. I have recently become a rather proud owner of a bone stock rather cherry 99 GT. Only grip so far is the bad factory tune! What kind of horsepower and torque increases could I expect over the stock 205? Is it possible for you to disable the traction control? only mod to the car is the removal of the resonator infavor of a straight pipe. No worries of E tests around here.
Is it possible to buy a pcm outrite from you or is my core manditory?
 


I sent an email around the 23rd of March and I have not heard anything from them.....maybe it's some Canadian Holiday.
 
i have the y pipe and two flow masters,i also have the 3.5 pulley msd wires and coils and also a cold air intake with 58 cfm bbk throttle body and also changed mass flow air sensior is there anything eles bolt on anyone can think oa before i go into the engine i want some roller rockers
 
so have you guys private messaged him or actually emailed him?? I plan on getting an overkill pcm in the future but if hes not responding that may not happen...
 


Hi guys. Sorry for the delay in responding to questions here as I don't get the opportunity to frequent the forums much anymore. If you have any questions, please email me at [email protected] and it would be my pleasure to answer them for you!

Peak horsepower will increase in the range of 10-15 horsepower on a mildly modified vehicle but more importantly is the increased power available at mid-throttle from the transmission being in a more correct gear (quicker downshifting), the improved knock retard management and the revised torque management, all which hinder performance significantly on a stock vehicle. The gains at part throttle are more significant, which is good because that sort of performance gain is much more useful as well.

I can remove the spark retard from traction control on some vehicles however it is best to turn it off manually.

You may keep the Overkill PCM sent along with your original PCM and simply forgo the refundable $75 core charge.

I checked my emails from the 23rd and there are no unanswered emails in my inbox. If you didn't recieve a reply, please resend your email! I would appreciate the re-opportunity to earn your business.
 
iam having trouble email will he dont respond does anyone else have this problem is this the right email [email protected] does any one have a telephone # for him
ineed to have him rework my pcm for 2004 comp g
 
This is very discouraging to hear. I'm currently answering emails sent late on Tuesday the 14th and from today. Either emails aren't reaching me or my replies aren't reaching you.

Let me know when you sent your emails and what email address so I can search for them, or email again or PM on the boards.

Thanks
- Will
