***Turbo Performance Works Piggy Back Info***
- Thread starter perfworks
- Start date
This unit Igdrasil will be mapped for optimal performance thruout the rpm band. It bases its values from whatever the user programs in the input and the desired output. The unit will use the O2 sensor to control the A/F ratio thru the inputs we are going to provide to it. The MAF voltage will be clamped to a certain degree whenever we see fit to get the reqiured amperage reading to the ecu for functionality. We will control throttle angle voltage for load input to the ecu along with MAF and o2 sensor readings.igdrasil said:
We are using the stock ECU inputs and outputs to our advantage. The stock ecu will still process the same information and wont be disturbed in performing its every day functions. The piggyback will basically go "around" the ecu to perform as intended from what the driver is demanding from the system.
There is no reason why you cant do it right and let it see catalytic converter efficiency. Its all a matter of personal preference. I chose to have a clean set up where everything is doing its job according to plan.Kooldino said:
just to touch up on a another note intended for beavis' comment on the O2 cel.
with a standalone you dont need the second O2 anymore so thats the way you get rid of the CEL on that application. with the piggyback the stock ECU is still functional for diagnostic and emmision related purposes. so it will still see the problem unless you go with the two above named fixes

We all know that the protege are not great on gas. Will this system also help with getting better gas mileage? If it does will it be significant? Also will there be advanced timing for n/a protege5?
your gas milaage is dependent on two different variables for the protege. one is that it is very efficient in closed loop keeping a good eye on A/F ratio. its when it goes into closed loop where it dumps fuel because it sees a load value thats great and is not tuned for a specific octane you may be running.hawkwind101 said:
the major problem with the proiteges is the fact that it has a very high gear ratio and that is killing you on the top end gas mileage.
get the diff. to about a 50 point difference in ratio and youll see an improvement without touching the fuel.
youll of course feel like you have less power in fifth gear but there is a trade off for everything you do

I would say thats pretty bad!
Civic 36/44
Corrolla 40/53
Sentra 33/46
And then there is the Protege 25/31
As far as I'm concerned the gas mileage sucks!

im still confused about the top speed aspect of this car, me and dave (PRO 5) top out at around 136mph...by saying top out i dont mean theres no power left in the car, because there is a lot of rmps left till the red....the car just SHUTS OFF when this mph is hit, turns off, nothing works, till i put it in neutral and let it go back to about 120mph, stuff it in 5th, and it seems to "jump" itself back to life...im guessing with a standalone this problem would be eliminated, but im thinking since the piggyback still uses the stock ecu, it wont get rid of the problem...that sucks for racing high speed cars on the freeway, like i guess corvettes, mustangs, or camaros.....

THANKS, and i hope this is so, so i can buy this instead of the microtech, thats one of the biggest aspect or factors im looking at right now....perf, are you gonna be doing a high speed run?? do dynos even do that?? if so, please see if you go above 140mph and how high it will go to red line, just to see what our cars can do....thanks
Iam going to have to test my P5 to see what exactly it is your talking about here. But just because it works with the stock ECU doesnt mean it wont fix the problem. Remember the unit controls what the ECU sees. we can adjust parameters and control fuel and ignition delivery so that the car wont shut off .duMb KeoLa said:
This is the first thing I'm doing when I go F/I. I'm dropping my final reduction for improved economy. The extra HP will offset the change in ratio as far as speed is concerned. You can turn any high-revving 4cyl into a big V8 suv in terms of RPM's. O/D on a suburban puts 75mph at about 25-2700 rpm's, as compared to our proteges.perfworks said:
