Re: New LE3 setup Dyno numbers

Great Numbers Man,
I almost went with the LE3 cam, but punked out because I thought it would have been too much for car on the streets and thought I'd have to rev too high to see its full potential....I was wrong When this stock engine goes, I will be getting that cam in a 383!
Congratulations!!!!

Tim

There are no more options in the OBD2 either and it's not closer to tuning an LS1. It's pretty much the same as OBD1 with a few differences.

Are you running a 58mm TB by the way?

I thought it would be half the time because it only does one part of the flash not the whoel T/E side I guess you would call it, just the e side? Anyways I heard just half is uploaded reducing the time by half.

If there are no more options in OBDII then I guess screw it, I thought there would be Ok LS1 conversion on LT1, change firing order and add a few sensors

No, OBD2 LT1 doesn't do segmented uploading like LS1 does. The read is slower than OBD1 and the write is just a bit faster. It rewrites both E and T sides. The T side is twice bigger than on OBD1, but it writes it twice quicker. The E side writes the same as on OBD1, so you get 75% quicker overall.
If you want your car to set more codes (that you will disable) than your OBD1, then I guess you could call it an extra option if you want, because there isn't much else different than OBD1.

I wish you good luck on the LS1 conversion.

Re: New LE3 setup Dyno numbers

Very nice numbers . We need to see it translate to the track now. I can't wait it should run very well !!

I thought the 12 bolt only ate like 4 or 5 more HP than the 7.5?

Re: New LE3 setup Dyno numbers

that graph looks like you gained some low(er) end torque after swapping cams from your old setup, is that true? what was your old setup?

If you're looking at 377rwhp numbers thats with a closed cut-out through a bone stock muffler for one of the runs just to see what would happen LOL.
