You can get the ECU into 'timing mode' by doing all sorts of revving and crap - I never got it to work personally.īut an SR ECU will idle at 15 deg if your idle is at all stable. It sounds like nistune is pretty quick and easy, and I have an lm-1 that my brother got me years ago as a gift, but have not really used it. I'm no dummy, and am reading and learning a lot and understand principles well, but don't want anything that is going to take a lot of time to get working. I like the idea of programming it, but computers aren't my strength, and I'm not super experienced with efi. To that end, with an unknown programmer of the ecu (I will try and find out) and certainly no way of checking what they did, is my best bet to throw these parts on my car (maf, inj's, cams, ecu) knowing that they ran well on another car, or is there something that is waaay better for not much $$ (I can't justify a lot of $$ right now for a track car that presently works fine) that would allow me to set it and forget it? It seems that 300 ish is a realistic number to get and still have the reliability I've come to appreciate and love. So I was wondering if I should get that program (or something else) and the cables so I can access these functions or if they are easy enough to manage without by using mechanical tricks (disconnecting tps, etc).Īs far as what I want to do to the car, it has been great, and I don't want to do anything that could compromise it, but I do want more power.

It looks like there are some programs (I read specifically about datascan) that allow you access functions such as locking the timing so you can time the car, dropping a cylinder at a time for diagnosing, turning fuel pump on and off, and others.

In looking at timing specifically, I read that you have to lock the timing in and it can be done two ways: through the ecu via a computer and software, or by disconnecting the tps and possibly revving it to lock it in. I believe there are probably two subjects here: how to 'tune' our cars best, and how to make more power with minimal fuss.
