Isn't it funny how two people can say almost the same thing but it sounds completely different and sends a different message?

 

thats hilarious, she'll be thrilled to hear it.

ur gonna start a storm by saying the 2.2 L is superior.

question: i feel a loss of some low end torque with the ap1 ecu. do u feel it to be the same as oem?

this is a dyno that deathsled sent me, showing that im just imagining the drop.

 

So is there any real benefit to revving the f22 to 9k? i mean they made it redline at 8 for a reason. is it just so you guys can say you rev to 9k?

 

The F22 IS superior. I don't know how you can really argue that fact... at least from a performance standpoint.

As evidenced above, I am not an expert on engine internals. What I do know is what's faster on the track. When we replaced the motor in the race car, we went with an AP2 and HP went up and lap times dropped. (We had an aftermarket ems with redline set around 8500 and fuel cutoff at 8600)

From what I've heard, the AP2 motor seems to be more reliable as well, although I may have undone some of that with the new fancy gizmos.

Shawn Church has dynoed hundreds of S2k motors and the AP2s always seem to have 5-15 more HP. (than an '02-03 AP1... the gain over the earlier models was even more significant due to less aggressive ecu mapping on the '00-'01)

So far, I'm very happy with the result.

As explained above... it appears to be more of a reliablility issue.

btw Lawrence, if deathsled says so, it must be true... he knows all.

(fwiw... there are a number of factors besides just the motor that can cause the lag you refer to. My dyno graphs on the old motor looked very different with different exhaust systems. Some fluctuated, others were very flat.)

funny how that works... huh?

 

so you guys put ap1 ecu's so you can rev to 9k, making it more reliable....? wtf

 

I didn't explain very well... I was saying that Honda limited the redline to 8k to make the F22 more reliable.

 

dyhppy: you are running too lean with that ecu.

You don't need any head mods to spin an AP2 to 9k. The problem with spinning it that high is dramatically increased sleeve wear. 8300-8400 is the most you should go.

 

Hondata ftw, imo, for AP2s....but the idea of a 9k F22C is intriguing to say the least.

 

so what of the AP2's in markets without a 2.2L?

8K or 9K?

 

all 2.0L are 9k
