I have had the LM-1 for a month and it works great and is very accurate. everything sounds normal, the only problem I'm having is hooking it up with the analog cable to the factory honda O2 harness and having it run the same. When I hook it up the car goes rich. and hondata and the hondalogger wont accurately recognize it. any suggestions on how to wire and configure every thing properly?




any suggestions on correct wiring?

First off I'm not sure if the wideband is accurate at ide because when i first start up the car and the engine is cold my afr is about 11.4 - 12.5 Once it warms up or you rev on it once they jump to 19 - 22.5 and I'm not sure why.

-sounds normal. stock maps run rich at idle when warming up (open loop).

While I'm crusing off boost the wideband is staying about 15.4 or so which seems a lil lean for having 35# injectors.

-seems normal since youre off boost. it may go to 19+.

I played with WOT and about 8-9 psi of boost and my air fuels were high. 13.5 - 14.7 or so.... Adjust the fmu richer only made the car run leaner. At that boost no matter where i had the fmu adjusted to it missed and ran like crap under boost.

-sounds like the fuel pump is giving diminishing returns as the fmu increases pressure.

On this pull i started turning left from a stop, as i pulled onto the road I floored it and held into the gas until about 90mph or so. The "X" axis of the graph is only a timeline I dont have the rpm logger hooked up yet. As you can see the fuel curve is very flat, I am very very pleased with that especially for an fmu. It goes to 12 afr's as soon as i hit boost...the beginning was me idling and takeing off trying not to roast the tires.

-ya that does sound pretty impressive for an fmu. 12:1 disc i assume?

-have you hooked up the rpm logger yet? is it included? a properly working rpm vs afr map is the main thing im looking for. i know someone that had to write his own script in excel to translate the raw data. that sux.

-what about ignition? might be time to step up to bigger injectors and uberdata/turboedit..

turbointegra22,

I'm sorry that I can't help you with that one. I'm really not familiar with any of that stuff but I do wish you luck in solving the problem.

XDEep,

Your the second person to tell me that those afr's are normal when not under boost so thank you.

Yes I know the fuel pump is probably diminishing returs as the fmu increases the pressure but I didnt word it as nicely as you...I'm glad to see people are agreeing with what I beleive are the problems.

The fmu is an ajustable cartech/begi part #2025. For an fmu I like it but the next step is a new fuel pump. After that I'll ditch the fmu when I get some money and run either a sub injector controller, and emanage or a full stande alone system.

Thank you for the info guys

you should look into the new Cobalt SS ecu.. its a super charged engine, so maybe it will be of some use to you. Or even a GTP computer?

Yeah thats a good idea in thought but unfortunatly it wont work...well it would but it would be too costly. The 2000+ jbodies can get a gm supercharger and an ecu reflash which I'd like to get. Unfortunatly you cant do that.... the cars changed in 2000 so the gauges and wiring is all different.

I would have to swap the whole engine harness, instrument cluster, computers, run high impedance injectors among other things as well and then have to pay to have it reflashed for the GM charger.

Good thought but I'm going to have to go another route. This summer I might just start a new jbody project with an ecotec but we will see

Nice man....I wish I had a WB02 .
That one looks awesome....the price ain't bad either
