N/A Tune Potnetial

[Edub1]

I've decided that it might be a good idea to install my Emanage on my stock motor so I can familiarize myself with tuning while I still have a little room for error.

I'd also like to see what I can squeeze out of the stock SOHC in the mean while.

Any suggestions on some good parameters?

I donno. You'd probably have better luck in the KA forum

welcome sir.

an all stock all motor K/A with an e-manage?

maybe if you are the ish you can lay down 10 horsepower to the wheels. its fairly common for a KA with bolt ona to see about 15 wheel horse with a nice dyno tune

so depending on how good you are i think 10 wheel horse on a stock motor isnt far out of possibility. but its gonna cost a lotta dyno time to make it there, or g-tech time....

The KA has quite a lot of room for tuning, simply because it runs rich as hell at WOT.

You can safely lean it out a full point (or more) a/f after 3500 rpm. You need a wideband to tell you whats going on, dont try tuning without one.

You can pick up a respectable amount of ponies, the ka24e runs as rich as 12-11.5 a/f in the top end, shoot for 13.2.

You don't think it can go up to 14? What about timing?

[deviousKA]

You can lean it as far as 13.5, but I suggest you shoot for 13.2 just because. 14:1 is to lean, your not going to make any extra power just more heat.

Set your base timing to 18 degrees, get some good gas in it and maybe some other octane boost and you may be able to get 19 or 20 degrees base before you start detonating under load.

You should only be able to get 18/19 degrees base with your distributor turned all the way clockwise. This is advancing your entire map, considering you will be using a piggyback that manipulates your maf signal, the ecu will not be reading the map exactly like it should. Generally by leaning your fuel you will be telling the ecu it is getting less airflow than it is, which it turn will be lowering your ecus calculated TP. This will change where it is accessing the ignition map, will be more advance (less TP) at full load compared to a regular ecu so be careful.

I see - The emanage will allow me to control the timing as well but I never was able to figure out how to get my distrubutor to turn. I was under the impression that the SOHC did this strictly via the ECU. Anyway, I can even back off the timing if necessary with the emanage.

Perhaps this would be a good idea if I'm detonating while still richer than stoich? I just hate to wast a perfectly good O2 molecule.

[deviousKA]

The distributor does not physically turn when the ecu advances timing. The ecu controls the timing of the coil, the distributor can accept a range of coil timing. This is why the rotor and cap contacts are as wide as they are.

The emanage would have to modify this ecu coil output, would be my guess.

You are correct.
