Delta Regrind on Practically Stock F22A6 car?

[Shadow1]

thanx for that info man. ill be sure to run it hard in a couple of days. i need to. i would take it down to the track but i know i would fail tech inspection due to the oil leaks i have. i think its the crank shaft seal.

anyways. ill look into getting that h22 TCU. never thought about getting one of those. i always thought that youd have to get the tranny also b/c they were geared differently.

owequitit:
- but how was it that you made your auto tranny shift at 6.8k - 7k rpms though?

By manually putting it in gear, and then clicking it to the next gear at 6.8K.

If I let it shift all by itself, it shifted at 6300.

When it was stock, it shifted at 5700-5800.

With I/H/E it still shifted at 5700-5800.

With H/E and the A6 manifold/PT6 ECU, it would shift about 5900-6000.

With H/E/A6 manifold/A6 camshaft/PT6 ECU it still shifted about 6000-6100.

When I put the H series plenum on, it started shifting at 6300.

I think Honda programs the ECU to command an auto tranny shift when power starts to fall off.

Since power wasn't falling off as badly, it was shifting later.

It wasn't the TCU, because the TCU was original, and the same, the entire time I had it in the car.

so i take it once i change the IM, plenum, headers, and exhaust itll shift at a higher RPM? so whats better: get the h22 TCU or the parts listed above? or both? lol

I would get the H23 TCU if it were me. Unless you have everything ready to rev to 7000 RPM or so. Plus, you will have to find a JDM TCU, because there is no OBD-1 H22 TCU from the US.

see cause right now i'm running a DOHC F22B head milled and the stock pt6 w/ stock tcu and it still redlines the same even when manually shifted....

that's why i was wondering what'd you do to increase the redline

i was thinking maybe when i get the chipped ecu working correctly, i can set the rev limiter a LITTLE higher and see what happens....

deev what do you mean about using all OEM parts on the block ?

[10thcb7]

btw what do you think a F23 could be wound up to with out spinning a rod bearing.

The rev limit is controlled by the ECU. You are going to want a P14, or a chipped and tuned ECU.

The rev limit controls how high the engine can rev, and the TCU control when the tranny shifts based on signals being received from the ECU.

So if it is hitting the rev limit, then you need the ECU. If it is shifting earlier than the rev limit, then you need the TCU.

Based on what you have said, I would guess you are bouncing off the rev limit.

ok so why would a 272 be ideal for the auto ? 272 refers to how high the power band is right ? So if I had a F23 @ max it would only spin to 7.5 and thats being crazy.

read back in the thread, it says NOTHING about the 272 being for auto

and yes, it bounces off the rev limit

i just changed my tranny fluid today and NO metal shavings AT ALL

or get a 5speed swap and shift where u like

u know u want it terence!!!

If it is bouncing off the rev limit, then a new TCU isn't going to solve that.

i was wondering, does any1 have any vid/sound clips of their/a CB7 with a 260 regrind? even a detailed description would do

lmao. sike. maryland traffic is too freakin bad for a 5spd. lol. plus i get on the highway alot and i dont want to worry about the clutch and all that crap. lol

The 260 will have a stock Idle
The 272 will have a loopy idle
The 282 Will barely idle at 1k rpm, you will have to set your idle at 1500.

The 282 does dont clear the oil valley in the F22 head.

The 272 emphaise on the top end power more, and the 260 are for mid-range. The 282 is for racing basically.

It's best to pair any cam upgrade with a tuned ECU.

But it depends on what you want to do with the car that decides on the cam you choose.

gona bump this

282 clears the f22a head perfectly. I'm running one.

I idle SOLID at 1k.
