Performance History
What to expect for 2005
This year I plan to perform some interesting modifications to my GT-Four. I have already prepared the engine to handle more power than it has right now. The fuel system is up to par, and I now have a Perfect Power SMT-6 to assist with tuning. The SMT-6 will be critical in my next round of modifications.
Most notably, I plan to convert the flapper door Air Flow Meter (AFM) into a Manifold Absolute Pressure (MAP) system for deriving fuel and timing maps. Until recently, the only options available to do this have been a fully programmable engine management system or the HKS VPC system. However, the SMT-6 can get by the traditional problems because it allows the user to tune 3 dimensional maps on a laptop. In essence, I plan to use the SMT-6 to convert the signal from a MAP sensor (taken from my Greddy boost gauge) to replicate the signal that the AFM would have produced. By doing this and properly tuning for all load sites, the ECU will essentially not know the difference and function normally.
From that point, I will be able to do some fine tuning, particularly with respect to reducing the injector duty cycle levels that the stock ECU runs the injectors at. I am using an injector duty cycle monitor, which has shown me that the stock ECU easily lets the injectors run at 100%. I hope to bring this down with the assistance of my adjustable fuel pressure regulator, to at least 90%, but preferably somewhere around 80% or a bit higher. I have a set of 540cc/min Supra injectors standing by, should I need more fuel once I tune for higher boost levels. My hope is that I will run a low 13 second 1/4 mile, or possibly a high 12 by the end of the season.
I have also begun to collect parts for much needed body work. Since I purchased the car several years ago, I have wanted to respray the car and fix some rust that is starting to develop. However, the engine blowing up twice made it financially difficult to spare the extra $5000+ that I will require to paint the car. Since then, the rust has continued to progress. I have now started to collect parts that I will need, including brand new Toyota front fenders, and used rust-free rear 1/4 panel cut outs. It is my hope that I will be able to afford a paint job now that I have finished University. However, I would very much like to purchase a house soon, so things may get put on hold once again. If you feel sorry for me, donate money! chris_dittrick@yahoo.ca is my paypal address.
Anyways, thats what I've got planned. Wish me luck!
