A'PEXi S-AFC II installed with dyno results!
 

I had the S-AFC installed yesterday and am very happy with how the Z is running now. My original intent was to just have the Z dyno'd because of a recent change of spark plugs which lead me to believe that it was running a little rich. I used to regularly experience slight smell (like burning oil) the first few times I would go WOT at any given time of the day. I don't know if that smell is directly related to running rich or not, but I can tell you that it is no longer doing it at all since the tuning with the S-AFC. I consider myself very sceptical when it comes to gains from mods on the Z, but the tuning has no doubt netted more gain than my exhaust, cold air, or timing advance. Now I also recognise the fact that the tuning has allowed for the best gains of those mods and that it is a combination of all of them.

Unfortunately the dyno only showed a 5 hp gain from the base to pull 3 and 7 hp from the base to pull 4, but it definitely feels like more than that. Today when I woke up I went for a drive and the Z doesn't even feel the same. The Z pulls up to 4000 RPMs as it always did but at 4k and above it feels undoubtably stronger. It used to really feel dead toward redline and it is much better now.

I was hoping to see higher numbers out of my Z, but was assured by the tuner that comparing my numbers to others was by no means an accurate way of judging the power of my Z. He told me that the variables and equipment used could drastically change the outcome of my numbers and that I could go around from shop to shop and eventually get the numbers I want to see. Actually all the guys at the shop were fantastic. I felt a little language barrier at first but we were able to work through that with little complications. I guess MORE POWER is understood by all.

Highest Pull

Nice A/F ratio! I'm hoping to get mine similar, but a little more in the lower 13's.

Good job!

Thank you for you post and this is good news for me. I've been wanting to purchase the unit but sceptical of the knocking sensor functionality being compatible with our Z. Were you able to get the knocking sensor operational?

Your A/F ratio looks nice and steady. 13.8 is good for NA. I was around 13.5 at 6600 rpms. 13.8 from 3000-5500 rpms. Tuned with xede. Picked up about 10 ft lbs throughout entire rpm range.

Where do you have the external computer display mounted at?

hey, I see you're in Victoria, did you get it tuned there? I'm just down hwy 59 in El Campo, and I've been driving into Houston to dyno, it would be nice if I could just go to Victoria to have that done (I'm also looking into the S-AFC II or E-manage to squeeze a few more ponies out of my car) - please PM me with some details...

looks good bill cant wait till you do some more mods and retune. *cough cough* twin turbo *cough* but i aint saying nothing else. later jason

its compatible it works on mine. used to show numbers till i tuned it now shows 0 knock all the time

Hey LaPuLaPu, your signature graphic looks familiar.

Hmmmmmm.... where have I seen something like that before?

For right now it is in the factory nav/storage compartment. I will be properly installing it after I figure out where I want to put it.

Just looked at your dyno....Didn't know ppl from San Antonio drove to Houston to dyno at Carboy. I've been a customer there since 1994...of course back then, they were at 59 & Bellaire. Now they're on Bisonnet. Jackie worked on my accord, teg, civic, and now the Z. Dayam I feel old. lol. Hit me up next time you plan to come down. Wouldn't mind meeting a fellow board member and checkin out your Z.

I suggest mounting the display in the factory sunglass holder. That's where mine is mounted.

Holy brought back from the dead..LOL. Actually I lived in Victoria, TX at the time and H-town was the preferred place to go. I wouldn't mind going back to Carboy for more work, but the drive from here to there is a lot longer than from Victoria to there. Jackie and Fui (<---however you spell that) are some great guys.
