ok guys, as most of you know I am building up my new engine, and I have this wonderful tweecer rt. Now I made some changes to this stock program that I believe should be good for to at least start the car and see if it drives ok. Now I know there will be a LOT more tuning involved to get a good tune and different types of tunes etc. etc., but I just need one that will allow me to start the car and drive it to break it in 500 miles so I can do some hard WOT runs to datalog w/o blowing the car up. I have the mark VIII mas and 48 lb accel injectors from josh. I changed them to 45.5 since they are made for 48 at 43,5 psi not 39 like the sho runs. I then want based on an article josh had on his site to make the low injector slope 10% larger (is there some function or scaler thats tells this thing about the 48 lbers that someone has?). I then made small changes for cid, idle, rev limiter etc. I also have a ton more boltons with bumped compression, now im pretty sure the computer will adjust for the cams and ported heads and such, on its own for now, but how do I tell it its got bumped compression? Also is there anything I did that looks wrong or anything else i should add to this to make it a little better? the parts in the pics are the only parts i changed everything else was left stock, so did i miss a section i should be in right now?

Stuff I changed:

How about this, where is this and did anyone do this already with the 48 lb injectors to save me some work :naughty:

2.2.2 Injector Cranking PW
The cranking PW table tells the EEC how long to open the injectors during cranking to start the engine. This table is in MS and needs to be scaled to match your injectors. Just scale the table up or down by the factor of how much bigger or smaller your injectors are than the injectors in the stock calibration you are using. For example, if you have 30 lb injectors and are starting with a calibration built for 19 lb injectors, divide 19 / 30 to get .63, and then multiple EVERY number in the table by .63 to make them match your injectors.

MORE: what do I put in for this field in the scalers?

2.2.7 PIP
The EEC base loop is executed every 1/PIP seconds. No mater what hardware is in your engine and no matter that you disable the RPM limits, you engine is never going to be able to spin faster than the PIP allows. But you can't just put in a million because the EEC CPU isn't fast enough to run 1 million base loop cycles each second.

your going to be running cams, right? secondaries are way too early regardless.

iv seen on dynos that thats where the tq and hp curves pass isnt that the best place? or do stage 2 cams change that? the 3.3 will pull more air then my 3.0L so i thought opening early was better. My old lpm had them opening at 3700 or so, i didnt burn that though that was the previous owner. What do you guys think the secondaries should be at?

When the secondaries open you should not feel a power increase, it should be linear. Mine are set at 4150, and you can hear the car get louder, but it just keeps pulling, theres no sudden 'jolt' of power. And torque and horsepower always cross at 5200 rpm.

If you're tuning on a dyno, you could purposely set the secondaries to open soon (like 2500) then a second pull much later, compare the graphs and you could get exactly where the torque curves cross.

I think Josh had a method to do it just in the tweecer datalogger, on the MAF settings or something. I'm not yet a tweec'head myself!
