Thread: 6262 dyno Results and freeway vid p30

If you had a tuneable ECU (B14 obd2) you would be codeless just with little change on the feedback flags
no egr
no O2 sensor
no egr temp sensor
no knock sensor
Feedback control value to 00
Just that simple

I WANT THAT! got some news for you guys. Will update in a couple hours!

Ok, so I went to have the car registered. I had the crank sensor fixed. Long story short, I had 3 codes. Knock sensor. O2 bank 1 sensor 2 circuit malfunction. and P1336 ignition or misfire. The CEL was off. Readiness status on Catalyst and EGR not ready. PASS!

I am allowed 2 not-ready monitors to pass, as long as the MIL isn't illuminated. SO IT PASSES! WOOOT. Super excited. Putting in the cams in a couple hours.

glad too hear that! my laptop is staying on till the results!

But that also shows up as "not ready" when connecting to an OBD II code reader, which in AZ equals not passable

Coheed, hurry up more updates!

Nothing?

I got the cams in, had to swap the harmonic balancer because the marks were off. They have been off for quite some time now. New one is on!

I put the 20v cams in. Everything went smooth. Started her up and lope lope lope. Only 10in vacuum. WTH. I have swapped cams a million times before without issues, but now I get a lopey idle. GRRR.

My buddies were over so I decided to fix it with their help, found the exhaust cam was off by one tooth, must have jumped timing on the first startup. Never had that happen before. Fixed it and went for a test drive after. Vacuum steady at 16-17".

Car runs great, even without it being timed yet, it was pulling really really good. I figured the 20V would have some loss of top-end power, but I don't notice any loss of power at all. Better than the SR16 cams? Hard to say, going to have to dyno it and see.

The 20V cams do have a smoother idle to them, for whatever reason. When measuring the cams, the Exhaust side looks nearly identical, but the intake side was larger by around .3" or so.

So everything is good. Got the new Pilot Super sport tires on it. They feel great. The cams feel good. Car feels good. All is good.

Did you gain any spool/off boost/boosting power with the low lobes?

What about surge?

What rpm are activating the high cam, also is there any notable difference in partial throttle?

So far, I have yet to time the car. but from what I can feel, the SR16 cams hit a little harder. This could be because of the timing being backed off, and also because the low-lobes are much larger.

I am reserving my judgement for now, but the car reacts to the VVL switching at a higher RPM a lot better than before with the SR16 cams. I want to be able to put the timing back up, but I have to get a timing light hooked up to some jumper cables so I can time it.

At least I can actually time it. Does anyone have a pic of their spark plugs after 3000 miles of beating that they can post a close-up pic on? Reason I ask, I have some heat range 8 plugs in there now. Here is what they look like:

Here is a heat range 6:


heat range 8










So these "spots" are detonation? They don't seem to protrude out like tiny balls of metal. And they have been in the car for quite some time, about 5000 miles or so of heavy abuse. Would this be a clear sign of detonation? As far as that is concerned... I don't know when it would have happened. It is weird because the 6's have more buildup on them, and it looks a lot worse. I haven't turned the boost up on these plugs without race gas. I run 10psi. So I can't see why it would be detonating on 8.5:1 compression on 10psi boost (8psi compared to sea level). What do you guys think?

As for now, the VVL is hitting in the 4500rpm range, which is quite a bit higher than the SR16 cams. They don't seem to "kick" as hard, but they do make more noise. Perhaps the kick will be better after timing is back at 15-17*?

Easiest way to tell is to put a fresh set in the car and do a couple hard pulls and shut the car off and pull a plug or two. If you got any detonation you will have black spots forming on the insulation.

That seems like a lot of buildup for 5k miles of use. But i guess it depends on the quality of the fuel your using. As far as the overall condition of the plugs, they look fine other than that slight spotting on the insulation. Doesnt look like the ground strap or anything else is being eaten away at all. So whatever detonation you had was probably very very light or it could just be buildup from use.

Again need a fresh set, do a pull, shut off, and pull plugs.
