Does emanage for N/A need 02 voltage fix?

[cewyattjr]

Nice. =) The max I saw with the P5 was 45 degrees of timing advance, and adding six would bring that up to 51 degrees, though the timing changes depending on load and all that, so who knows for sure. =) How many miles do you have with the emanage on, now, out of curiosity?

Hmmm, so maybe I'm too aggressive. I'm not hearing any knocking, but that may not mean anything. There's a screenshot on this thread where 1FASTMSP has his set to 5, so I thought 6 wouldn't be too radical, but maybe I'll pull it back until my MSD knock alarm thingy is in.

I've driven it to work for 3 days, so that comes out to about 200 miles.

Naw, you should be fine with 6, easily... If an MSP can push 5 without any problem, a P5 can probably double that safely, and like I said, the MP3 ECU is CRAZY advanced, ignition wise, and those run fine on 91+ octane fuel. =)

Does the E-manage runs good?

Did it need anything to be installed, or just injector and ignition wiring to connect and then to tune?

Yeah, so far so good! Right now, I'm only tuning ignition timing and not fuel, as I still need to get a wideband 02 and A/F meter before I start messin' with that. I did put in a MSD knock alert so I don't blow anything up.

Really that's it, I just hooked it up. The only thing is that you have to put a 100k ohm resistor between the MAF wire and ground.

Also in the "for what it's worth" category, since I upped by ignition by about 5 degrees my mpg has dropped from about 27 mpg (mixed driving) to about 24 mpg (mixed driving), and now I'm running 93 gas. So, at some point, I'll have to ask whether it's worth the extra monthly $$ just to have a bit more pep. On the other hand, I could back it all out, and just leave the emanage hooked up for now and figure that it is good preparation for forced induction at some point.

Hmm.

I'm just thinking could I get about 10hp more with racing gas from my car which has ported head, full exhaust and intake system? Specially down low?

Ok, so I'm thinking about this and I have to wonder if the ECU is dumping in more fuel to make up for the added timing. Are you constantly having to adjust it, or did you set it and leave it? Have you noticed a gradual loss of performance from when you first made the adjustment. Wish you had a WB or were on a dyno to see what the AFRs are doing and how the ECU is reacting. Have you checked the timing with a light to make sure the ECU's not learning your adjustments? That's just the questions I'd like to have proven on a NA car. I hope it's working for you, and I'm glad you're out there being a pioneer.

I'll get a AF meter with a wide band O2 before long, so can definitely see what's happening from that end. Most likely the mileage change has something to do with my own driving style changing in response, tho'.

So, I do have a timing light, but never hooked it up to this. Is there a hash mark on the crank pulley? I was suspecting there might not be since you don't adjust timing the old fashioned way on OBDII.

Bah! I'm used to dealing with v8s, forgot about that. Yeah, you could use a paint marker and mark the pulley, index it against something on the block, a bracket or something, but then you'd only be able to see changes in the timing, but not know what they were. I'm not sure how you'd verify the timing, maybe someone who knows more about ems's will step in. That issue has come up before, but I've never seen it proved that the ECU won't compensate around the timing, or fuel for that matter, on a non-boosted car. I hate to be so skeptical, I'm glad you're out there trying it and I'd love it to work, but all of the cars I've seen running the Emanage so far have been boosted, and they get around the ECU's aggresive relearning by altering the signals only under boost. Good luck, and keep up the good work!

bump for an update on how it's running??!?

bump for some updates. I will be installing mine soon.
