I'm looking to have my PCM programmed by somebody local to me, but want to make sure I'm thinking of everything possible without going overboard. I have a 2000 SSEi, with a 3.4 pulley, a custom FWI with 9" K&N, 180 degree thermostat and 104 autolite plugs (2 heat ranges colder).

Other than the fans setting (for the 180 degree mark) and removing the speed limiter, what else can I do? Would it be safe, without higher ratio rockers, to up the shift points? What about something called the 40 MPH lag? Can the ride be changed to firm or sport?

I want as much performance gain as I can get with the mods I currently have. I don't want to do anything that could possibly hurt the car.

Thanks in advance for your input!

sup 00indy,


from what i heard, in addition to a removed speed limiter and fan point for 180 stat.

you can get firmer shift, and its still reliable, theres also skip downshift(going from 4th to 2nd and 3rd to 1st)

better air/fuel mix.

theres more options you can have but thats all i know(according to your mod)

i plan purchasing a pcm myself ,and doin 1.9 rocker next year, to go with my 3.25 pulley(not installed, 3.4 right now)

foghorn or rogue will give you more accurate options for the PCM, they know there stuff

or anyone else who have a PCM.

goodluck

You would not want to raise the shift points without adding stronger valve springs. Also, with stock rockers and cam you're not going to benefit any beyond 6000rpm as the power drops off significantly thereafter.

The 40 MPH 'lag' is really a transmission issue. The stock PCM does not allow a downshift into first at this speed (I think 38 MPH is the max). Because of the power band of the engine and the gearing, it seems to have a flat spot at this speed.

Based on your engine mods you would need a 'standard' PCM as far as performance goes though there is a lot that can be done to the tranny shift charactoristics to improve response.

Cheers,
