ka24de/e stock ignition cure/map.
Hey guys, I asked this in sohc kat section but maybe this is a better spot. Does anyone know of or have a stock ignition curve or map for ka24de or ka24e?
Many thanks.
Many thanks.

This is a timing map for a S13 KA24DE:

Thanks Adamky, your the man.
This a stock curve or modified?
Cheers.

Thanks that's great.
Wow, It has a lot more advance down low than I was expecting.

Let me double check it but I'm almost positive that's the stock map.

Re: ka24de/e stock ignition cure/map.
Meant to respond but never got there. I would feel comfortable using the ka24de map as a safe start. The combustion chamber design for the single jingles dictate that we will have a few degrees more advance than dohc kas. For reference, peak torque and 0 psi, I run 26 (or maybe 28) degrees (where the dohc shows about 24).

According to my notes, that is the map for a '91 KA24DE manual trans.

Re: ka24de/e stock ignition cure/map.
No that's great. Not doubting you guys, I was just a little surprised at the the amount and quick increase of advance at low rpm.
Excellent info. Many thanks. I'm sure this will help.

Great, now I have something to base my single cam maps off of, not just random guessing!
How does the load relate to psi or kpa? Any conversion that would be useful?
EDIT:
My only concern now is the drastic differences I have noticed in the mid rpm, mid load range compared to my map that I beat the crap out of with no reliability issues or signs of detonation.. After translating that map to my tunerstudio map, I am seeing up to 10 degrees difference and more in other places. I do know that I didn't translate that map as seen above perfectly over to my 12x12 map, but that is a big difference in timing, big enough where I lowered the majority of it by a few degrees. I will attach the tune that i modified from the stock one provided in this thread so you guys can take a look if you'd like.

If you are using a MegaSquirt, grab the timing map from the MSPNP base maps.

We didn't try translating the stock map into MegaSquirt format; they were generated by dyno tuning relatively stock engines.

Awesome, Matt! Great link there, i'm not sure how i haven't stumbled upon that yet, but that sure answers my questions. I feel much better about my ignition map now!Matt Cramer wrote:If you are using a MegaSquirt, grab the timing map from the MSPNP base maps.
