necisito ayudo ahora por favor!! Ghost, Cocoa, Blackie, Wilp99!!
Alright so I got my VAFC installed with the harness that showed up today, and I go through all the initialization settings and set them. Then as I'm browsing through the settings options of the VAFC I come across the VTEC engagement part and I notice that it's set at
Low -> High 5400RPM
High -> Low 5800RPM
and I'm like I know that ain't right, but still nowhere in the initialization settings does it say to adjust the VTEC point for my specific car even though I adjusted other setting specific to my car. So I was in a dilemma, do I go against the instructions and adjust the VTEC before the first time starting the car or do I change what appears to be obviously wrong. Normally I'd go with the latter and then I'd fuck something up and it would break, so I didn't want that to happen so I started the car and very nervously took it for a spin around the block. I wasn't going fast enough on the first leg of the lap to engage VTEC so on the way back I decided to keep it in 1st gear. When I do this I notice that as 3800RPM comes around ain't nothing happening no sound, no pickup, no nada. I then cautiously let it go up past 5000RPM and it seems then as it might want to switchover but it doesn't sound right at all so I quickly lay off it and cruise home.
So what I'm getting at is I need the H->L and L->H engagement points for VTEC on the 3.0. I need more than just 3800RPM. I can drive fine just I'm not gonna go higher than 3500RPM, other than this everything else seems fine no check engine lights or anything.

I dont have the VAFC hooked up cause it doesnt do any good on the J32's ecu. If it was hooked up and on, then I could tell you the settings.
Anyone want the VAFC2 pretuned for my car for $200? Tuned with I/H/E/P and vtec engagement at 3800rpms.

L -> H: 3500
H -> L: 3400
does that sound about right? I thought it might have been a little low but then what do I know.
#18
Well like I said before it's used but it hasn't been used so it's new. How did you reset to factory settings, I did the initialization thing which for me was under etc which I was under the impression that it reset all my settings. Ghost I'd like to know what you have your crossover points set at, I'll probably just set them to that. I just tried the 3500, 3400 and to me it seemed like the crossover point was a little low, IDK if it's cause I thought it was too low before I tried and therefore my mind is playing tricks on me and making it seem like it's too low or it really is. But either way I got VTEC back. I remember testing it with my friend where the VTEC kicked in and I told him it was 3800 and would demonstrate by keeping my engine revs in the 3800 range while driving. Shouldn't this be in the Helm's manual somewhere, can't someone check. I've googled it and search on this forum and the other and can't find any definite answers.
Oh sorry ghost I forgot I don't have the same username I used too, I'm the one that PM'd you about the location of the ECU a few weeks ago, thanks again for that!!

I did that, and then did the initial setup, and it worked fine, but I have the VAFC2.
did you get tit used or new?

As long as you have the oil pressure it engages based on the engines RPM and not the throttle position. I often keep the engine in VTEC in 2nd gear when trying to get through traffic. When VTEC is on and I'm above 4000RPM in 2nd gear the car jumps foreward when I tap the gas, this is not the case right now with my engagement point set at 5400RPM. If it was based of WOT it would switch to VTEC right away as soon as you floored it from a red light.
Next thing, maybe you didnt preset it to stock settings? Or is this new?

No without the harness you will have NO SLACK AT ALL so it you want to splice wires you gonna have to install extra wire to make the original wire longer so you have room to play with. You'll have to do this for every wire, and you don't want to fuck up once or you'll an engine light and then you'll have to troubleshoot it. FUCK THAT I ain't got time for that!! With the harness it it's a fail safe 10-15min install without out it's a grueling highly error prone 2-3 hour install.

It's new in the sense that it hasn't been used before unless it was used with a harness and they never spliced the wires, cause the wires are in new condidition. It was set to a 4 cyl with 5400RPM Vtec engage, then I set it to 6cyl like the manual told me to and left the VTEC where it was then I decided I wanted to clear my settings I did that but when I did it was still set a 6cyl with VTEC at 5400RPM, I'm gonna read more but I thought that the initialize option did that. maybe I didn't do it right let me go try it again hold on I'll be right back.............................................. .................................................. .......................... Yeah no it didn't work, it set's VTEC at 5800RPM and 5400RPM respectively. That might work if it was 2000RPM lower but no. So I set it at 3600 and 3500.
#23
But I 'd really like to hear from anyone with a J30 with a VAFC I or II what do you have your VTEC set at, it should be the same for both models. In fact I don't care if you don't have VAFC, if you got e-manage, Unichip, hondata I don't care it's all the same.
#24
so, when you initialized it did you turn it off then back on again?
what you need to do is initialize all settings, then turn teh car off, then back on.
then setup the # of cylinders, tps calibration, and other stuff, then don't mess with anything else and just drive your car a little bit. do some cruising, then some WOT.
if everything runs normal, don't touch it till you get it tuned, lol.
I can't remember if the vtec engagement settings were blank or just had dummy values in there when I reset it.

are you talking about the V/T info in the etc. section or the "VT set" in the settings section?
in the v/t info section it says 5800 for L>H, and then 0 for h>L. Those are just the values it reads everytime you drive. they are irrelevent.

Daniel, I dunno if my PM went through since you have a new account, but did you figure out what obd the 97 3.0's have? I think you have a 98, but can't remember for sure. Please lemme know which harness i need to buy and where you got yours from.
#28
I have VAFC2 on the J32 CLS. Yes to reset go to initialize under "etc". When I initialize mine, it always sets it back to a 4cyl setting. I found this out by messing with it, after initialization I changed JUST the VTEC engagement point...I found that VTEC kicked in at 3800 rpm even if I had it set at something different (L<H 4600k, H<L 4200k). After switching it to 6 cylinder, VTEC engagement worked as it should. What is the factory VTEC engagement for the J30? I ask because if it is much lower than stock, you will need to take care of the vtec correction factor also(vtec unmt). Otherwise, although the engine will go into high cam when desired, the ecu will not treat it like hi cam because it does not recognize it without vtec correction. There is a lot more involved than just changing vtec point and messing with the a/f ratio. I have messed around and found that a lower VTEC engagement with adjusted a/f is beneficial in the midrange, but seems to hurt the upper range. Since our cars were designed to excel in the upper rpm's of course. So basically, the performance is the same if not worse. My experience so far has been up and down, I am going to take my car to a tuner as there are many variables involved for a proper tune.
#29
Trial and error is the best way to go..Although when I thought I had it it all setup perfect (to make it not as deathly lean up top), in short time I consistantly get a rev limiter at 5500rpm. I don't like our ecu to begin with though. When I first went to get my car stock dynoed, after hitting 3rd gear rev limiter the ecu cut power and torque by around 25/25. Keeping the car on and fan cooled for 20 minutes did not help. If you turn the car off then back on to reset the ecu though, back to normal. Weird shit I must say.
#30
oh yeah, and I should mention something too.
before the VAFC your car won't engage VTEC until the car is at least slightly warmed up.
if you alter the vtec engagement with the VAFC it iwll engage VTEC after that set rpm NO MATTER WHAT!
I noticed that if I accidentally let it go past my set rpm when the engine is still cold it will lose an assload of power. I think what actually happens is that it tells the ECU that it's engaging VTEC, so the ecu adds a bunch of fuel for the bigger cams, bt since hte oil pressure isn't high enough yet it doesn't actually switch to the bigger lobes and thus runs very very rich.
either wy be careful not to do that, because for all I know it's causing more damage than just runnign rich.

You can not tune the CLS ECU with a VAFC. The ECU automatically corrects itself when the info is leaving the ecu. You have to trick the info coming into the ECU in order for it to work, Greddy Emanage is one of the products that can be tuned with the CLS ECU. I forgot the other one, brain fart right now.

This A'PEX digital fuel computer combines fuel computer functions with a VTEC engagement controller. The V-AFC2 features a user-definable, eight-point, adjustable fuel curve that can be set in 500 RPM increments. The range of fuel adjustment is /- 50% at each of the user-defined setting points. The Fuel Adjustment function considers wide/narrow throttle and low/high camshaft settings, from which four different fuel maps are created (wide-low, wide-high, narrow-low, narrow-high). The integrated VTEC Controller adjusts the point at which the engine switches from the Lo to Hi cam during acceleration, as well as when the engine switches from the Hi to Lo cam during deceleration.

I got to go to work so I don't have time to reply to all this but thanks guys.
Hopefully I won't need this info after today cause I'm gonna try to get a dyno and street tune done today, either that of finally get my rims and drop installed, but hopefully both.
LATER BITCHES!!

I think pin wise OBD2b the connectors have 32 pins, 25, 31 and 16. Not necessarily in that order but close enough. check your ecu cause it will say in the connectors 25p, 31p etc.
#36
ok I just looked in the manual for my VAFC and it seems to me that OBD2a is missing the 25 pin connector but it has the 32, 31 and 16. or you might be h2-a which has 26p, 16p and 22p. your either h2-a, h6-a or like me and then you'd be h7-a which is obd2b. the one I mentioned above is h6-a. Get a VAFC II manual and everything I said will make sense.
