High RPM Ign Timing

[hotrodj]

About how much timing do yall run on your F22A's? Im currently at 31-33 degrees at 5k+. It stops pulling after 5k-ish also, Im thinking its cause my A1 intake mani.

The motor is a JDM F22A, with a A1 intake. Stock exhaust with no cat, and a straight threw muffler. Stock intake/box. 93 octane gas.

Im tuning it on Crome. With a chipped P28, with vtec disabled obviously

Reading this will begin shed some light on relationship with RPM, ignition timing and loads.

Oh boy. Im well past that, Ive tuned many cars. Thank you tho.

Im looking for others experience, Im new to F22's. Idk if the basemap I found is a legit starting point. Im confident in my part throttle map, it runs pretty good. But im unsure of whereabouts the stock map has the timing on the top end. Im not gonna be on the dyno till I do some actual motor work.

Didn't you say you are using PT3 on Crome?
Didn't know you can do that........

I fixed that. P28. Was running the reg pt3 till I plugged int eh chipped P28 this evening.

OK.

There's a thread by a guy who is/was working on developing a software to tune PT3/PT6. I thought he had completed that.

I havent heard about that yet, Id be glad to test it if some wants to chip my pt3 for me lol I had this P28 sittin here so Im messin with it, runs and drives around and idles just fine.

Ill be installing a wideband as soon as i get a new controller for my spare AEM UEGO. I need a Ostrich yet too. Im spoiled by my S300 in my Sol.

It isnt going to keep pulling after 5k because peak torque is in that area. Amongst other things. That intake manifold isnt helping.

Do you have videos of any of the cars youve tuned? What systems do you work with. Just curious

Just a drag racing vid of my D16 Sol, bad launch but hung right with a boosted AE86.

I use S300 on the Sol, but Ive tuned quite a few cars with Crome.

I figured about the intake after I been looking at dyno graphs of similar motors lol I ran it up to 6k or so the other night, didnt run great lol Ever since then Ive had this issue with it running crappy at low throttle/rpm. Ive tried adding and subtracting timing in that area. Ive tried p28 base and p30 base. Ive tried p14 timing maps, and no luck. It runs perfectly fine with the stock pt3 tho.

I just found a Uberdata map that looks decent Im gonna try next time i drive the car.

Planning on swapping to S300 after the summer and strapping on my H1E ive been sitting on lol Gotta get a mani yet and a turbo cam.

^^ I just sent you some base maps for the f22a, one should be for crome, the other for uberdata. Also in regards to the factory timing maps, you can get an idea by visiting: http://www.pt-tuner.com/wiki/index.p...al_Programming and going to the 'text tables' section for Ignition timing, unfortunately as of writing I do not have the axis's completely figured out, but the side for the rpm scale should be as follows:
500, 699, 849, 1000, 1300, 1500, 1799, 1998, 2226, 2500, 2701, 2995, 3498, 3997, 4496, 5000, 5498, 5990, 6510, 8012

^^ This information can also be found in my Development thread.

Gonna be reading that thread tonight! Thanks

Quick ? Is there a difference in anything I should change on my tuning software/BIN because of using a P28 with p28 or p30 base? Obviously I have vtec disabled, I have closed loop disabled too cause i need a new o2. Gonna install a wideband soon tho
