Custom Burned Chip
Well guys, the time has come. Overhaul Gasket Set coming one day. Porting will be finished this weekend [as long as I don't run into any more snags]. And I am going to pick up a Torque Wrench this weekend, clean everything up and start the install back up. Since I really didn't change a whole lot of stuff, I am going to keep the stock PROM for initial start-up and for the driving test. That will hold me over until GM Tuners gets everything squared away [or until I know everything is cool to throw the chip in].
Now, in my Top End Rebuild thread, I mentioned I was quoted $160 for the whole schebang. Well, this is what it includes.
- Moats G3 16 Bank PROM Switcher
- EZ Remote [so I can switch on the fly]
- Three Programmings [more on this in a sec]
Now, you may be wondering what this stuff all relates to. Well, this means I can have UP TO 16 programmings and switch them on-the-fly [kinda doubting this.. but all I need to do is drop the car in Neutral, shut off engine, switch, start engine, back in gear I go.. not difficult]. The Remote makes it so I don't have to switch the programmings on the ECU itself.
The three programmings are for: Economy [I want to have the highest Fuel Economy on an 87-91.. we'll see how this turns out], 87 Optimized [Have the maximum ** of timing for 87 Octane.. and up the ante on some other various stuff, I think], and Race Gas [Self Explanitory].
Here'* where I need you guys' help. Economy? I don't know what constitutes higher fuel economy from programming. I'm guessing retarding timing? However, I do not know this. I just want to have some serious fuel economy.. not too interested in power with this prog. I know I will be putting a lot of miles on Pearl, and power isn't always going to be necessary.
87 Optimized? Not quite sure of the limits of 87 Octane Fuel. A few Hot Rod Magazine articles state their engine started detonating at 38* with 87. Not sure if that applies to all engines and whatnot.. but is that a good limit to stop at? What about Fuel Maps? Could the engine use more Fuel or is the AFR good stock?
Race Gas? This is going to be one sick tuning. May only get used once or twice, but I want more timing than friggin' imaginable. I'm thinking lengthening the fuel injector pulsing and increasing spark duration [if possible] will be real nice with this. All I know is I want this sucker to really come alive with this tuning. I want it to utilize the most timing that is absolutely possible.
I also have not gotten an answer from Ryan [at GM Tuners] about what all is configurable on my ECU. Does anybody have a complete list of this? I really would like to know what I can change, and what I cannot. Any list will help.. I really don't know where to start with changing stuff, and I don't want to go into this blind [not that I don't trust Ryan, I just like being educated on everything I can be educated on].
