What all is involved in ressetting the ecu? ..I'm liking all of these good clean legal ways of boosting hp. New to me.

 

See if you can get your money back on the K&N and spend it on gears...that is the best performance mod you can do.

 

K&N was cheap.. just bought the filter and did the rest of the rigging / fabrication myself. by gears do you mean altering the transmission?

 

Regearing the diffs

 

ah gotcha. Well my hands are kinda tied there. my jeep is my daily driver and my daily commute to work is over 80 miles round trip so I need to maintain highway driveability. my whole goal was just to see what all i could do to make sure that after 200k miles my engine is still performing the best it can.

 

Like i stated before there very little that can be done to free up extra poni's. To keep it running in top shape is to leave it "stock" and keep on top of your regular maintinance needs..

 

 

I don't understand how this works, I guess. If the ECU relearns in 50 drive cycles after a reset, why won't the ECU relearn in 50 drive cycles without a reset? My understanding is that the ECU constantly relearns based on feedback it is receiving from all of the various sensors. Is this not the case?
If you change your air filter, do you need to reset the ECU? Won't less restriction from a clean filter affect fuel trim?
Please explain how this all works. I thought I understood how adaptive memory works, but apparently, I don't and the techs who explained it to me don't either.

 

Regarding the 80 grit intake and smooth exhaust porting, I'm referring to aftermarket work.

 

I had my head professionally ported/polished and did the intake myself, I read the post about the 80 grit before hand, but if you've ever de-gunked an intake with 200k plus it's easy to see why polishing is important in the long run. There was an 1/8 inch plus of accumulated goo, using anything but a polish will only hasten this condition. I got a measurable response (although I didn't actually "measure" it) from the work I did. Admittedly, I also added dyno max headers and pipes.....also adjusted the kickdown and upgraded fuel injectors, but I am here to tell you, short of stroking it, it's the way to go (and I am coveting a block to stroke.....cause it just ain't enough!) /

 

Sorry I have no answer other than I was just throwing ideas out there. The pictures were from a stroker engine, If you have a stock engine just sanding to make it smooth is called polishing I think ??? Again I`m not recommending you do this just given what I`ve heard. I think a Cold air intake would be more than enough on a stock engine.

My opinion about throttle body upgrade: Carb only as the gas could use more swirl and time to mix with the air but MPI needs no such gismo.... This makes sense to me anyway but I`m no scientist

 

Ok I get what you mean now, Use 80 grit and nothing smoother or the air will stick to the walls...

 

You can always add a couple RUBICON stickers...I heard they add like 55hp right out of the envelope :P
