Need a tune in n.ga/se.tn

[rioredstang]

I need help getting a tune for my n/a ka24de race motor. I have a new motor and I don't want to kill it while I learn to tune. I have a chipped Emance ecu in it now. I would like to run at Road Atl. on 3/19 so my time is limited. I would think there would be several around Atl.
give me a call 423-316-1803

http://www.forgedperformance.com/ is one of the better shops in that area imo. They are also the only F-con tuner on the east coast.

if the stroke is the same but the compression is higher. just lower the timing accross the board. I would lower it 50% everywhere. Might run like **** but it will get you to the dyno in one piece.

Super low timing is bad. If your AFR is fine from the previous tune, then just knock the timing back a few degrees(like 4 deg or so for a whole point bump in compression should be fine).

Don't drive super hard until you can get it on a dyno if you're that unsure of your skills in tuning a motor.

I understand that it's bad for turbo cars but , how bad could it be for N/A vehicules?

[Def]

Depends on how crazy the motor is. If it's a <12:1 CR engine then I don't think there's a huge risk in trying to tune it yourself. Just put it on a dyno and slowly work up the timing and see how the motor responds.

AFR should be cake with a MAF, aim for about 12.5:1 at WOT on a NA motor, and you can go a tiny bit leaner at lower RPM, but it's easier just to get the K value spot on then make the fuel map linear IMO.

On an S13 KA ECU, if the knock sensor isn't disabled, then don't worry about it. Emance doesn't know how to tweak the knock threshold tables, so it'll still have the original conservative thresholds. Pull a few degrees, let the knock sensor take care of the rest. Fuel on the rich side if you're really worried about it.
