Default Link help....

Ok, i got the car started, everything is good at idle. Noticed a couple things:

a. Stutter when gas pedal is abruptly stepped on from a stand point
b. The Link is pulling something like 46 degrees of timing @ ~3-4000rpm.

The engine is a stock 2001, stock cams, and the map i have is for the COBB cams. You guys think i need another MAP or would this one work good? I need to do some tuning and datalogging. Well, thanks for your help in advance.

~Anthony.

If its pulling that much timing, it means it thinks you knocked repeatedly in that rpm range.

What setup do you have? Link+? T3/T04? TD04? Bigger injectors, FPR and pump? etc...

Have you switched the a/f sensors? What is the a/f ratio being reported?

I have forgotten the terminology for the Link, but play with the "tip-in" settings. There's a setting for when you step on the throttle, how much fuel to add in. If it turns out that you are adding too much fuel here, then check your plugs to see if they are fouled.

And yes, it sounds like you are knocking, and badly. Can you post a datalog? Use the stock timing settings that comes with the hard-coded Link map. Again, check the a/f ratio and adjust accordingly.

Link+, stock 2.5 internals, 2.5" full exhaust, SX FPR set to 40psi, 440cc RCs, Ludespeed III kit.
The knocking, i can hear. It doesn't happen after 2500 - 3000 rpms. I take the car datalogging but not for long. I try to tune but nothing happens. I might switch the COBB cams in the heads over the weekend. As of now, Bill at I-speed will email tune the car. But the one thing I am afraid of is, since the engine was from a rollover car, the timing might be off. I have to check and make sure everything points to the sky...

I can offer up a map of mine. I had the same setup as you.

http://67.67.169.97/linkmaps/good_one.pcl

Try that, that was mine that I used for a few months and the one Graham started with.

wcbjr - That map looks like it's good. I didn't hear the car knock or anything. I am still datalogging tonight and see the results. I also changed O2 sensor, and spark plug wires. Also cleaned the residue off of the coil pack for cyl #2, it was black and blue.
Thanks for your help everyone!

You've got an L? Unless you did a 2.5 transplant, I would not use my MAP.
