Your tuning method

[Super1800GTR]

So how do you initially tune your car when you 1st install MS? I've read through & even tried using Matt's method on my white car. Unfortunatly I've had little/no luck getting a better tune. Part of it is due to the fact that my car's current setup isn't ideal. Both of my MS'ed cars are over rich. .7-.8 V according to the narrow band sensors ( I know I need to install a wide band... waiting on new exhaust). Another disadvantage I have is I'm doing everything myself. I don't trust ANYONE but my father to help me & he's usually buisy.

How do you tune your ms by yourself?

i do it very carefully on closed roads, drive with laptop on ur lap
and tune on the fly.

or better tyet get someone to driver ur car and have full controll on laptop

i use mattdupuis/my excel worksheet to datalog and modify. i start logging, drive around town, then run through the spreadsheet and make necessary modifcations. then I repeat the process. I tuned the ol' wagon from a pretty rough map to fantastic in three runs. of course, this really requires a wideband... i tried doing some tuning on volvorod85's car with a NB, and its virtually impossible to do correctly (i succeeded in making that poor thing put out 1.48v though :cool: )

Let someone else drive while I tune via laptop/Wideband in real time.

Theresa was pretty good at it for a while too.

I'm exclusively using the Poi's spreadsheet with my wideband O2 sensor. I have it set to output the AFR (i.e. voltage of 1.47) and I don't use the O2 sensor for EGO correction. I only use it to datalog and tune.

Do you have a wideband O2 sensor? If so, replace your narrowband with it, since you can mimic the narrowband with one of the outputs. If not, get one. You don't really need to wait on a new exhaust to use it.

I don't know how I'd tune without it. I don't really think I could tune effectively on the fly at all.

my damn pre o2 leaks are killing me :-( :-(

This may make me sound like a tard, but don't you need a WB controller to use a WB sensor? Two 87's:
You say to just replace your NB with a WB sensor, and you're good to go. You do need a wideband controller too don't you? Am I missing something here?

MS up and running, figuring out how to tune with NB!

[ovlov760]

Yes, you need a wideband controller. Before wideband I started by using other peoples maps and then tuned as much as possible by monitoring spark plug condition, nbo2 and the knock sensor. You really need wideband to tune for the best and safest performance.

Yeah... sorry for the confusion. When I think of wideband O2, I assume there is a controller involved. What I mean is that it uses the same size bung and goes in the same position in the exhaust. It can also be used to mimic NB for any functions that the NB was doing.

So what I was really telling Rob was that if the only thing holding him back is that he wanted to do a new exhaust at the same time, then he should take the plunge and install wideband in his old exhaust. I regard it as essential for tuning, since that's the only way I've ever tuned. However, I suspect that the cost of a controller and sensor comes into play. They're not cheap.

Wideband is the ONLY way to tune efficiently.

I do ALL my tuning in real time, back road runs, usually by myself. Though it's alot easier when my brother drives and I tune. I set the laptop on the passenger seat and usually mess around in 2nd and 3rd gear. It depends on what I'm trying to tune, if I'm tuning boost I'll use 3rd gear because you're in it longer before redline. Floor it, watch wideband and road, right hand on the shift and up/down key's until the wideband reads happy. Repeat. I do this at all different boost levels, usually I don't even have to floor it because I get full boost at like 1/4 throttle. If I'm tuning for steady speed driveability I usually go as lean as I can without bucking. Do this at all different KPA points on the map. If I'm tuning 70kpa I'll start at 1500rpm and using the throttle try to hold the car at 70kpa while accelerating up the RPM range till redline, tune on the way up. Everything below 85kpa doesn't need to be richer than 14.5 in my experience, as this is very little load on a boosted motor.

I wonder if left foot braking would be an effective method for tuning boost...... Then it'd be kinda like a dyno.

[Hank Scorpio]

Eric (and guys in general) you can do a wideband now that will plug right into MS for 200 bones.

Those are pretty impressive. When did that come out?

Just the info I'm looking for.

eh.

month-2 ago. Its a sweet idea and just the ticket for people who dont nessicarly need a gauge to read it, they can plug it right into their EMS to do the same deal.

[The Aspirator]

Yeah Doug, that thing is awesome. Definately the perfect thing for all MS'ers who don't have a wideband yet.

[Morley]

Mine seems to be turn up the ignition advance and boost, and retard when something blows. Most expensive and fancy solution :-P

I bought one of those suckers and hooked it up today. Got my brother to drive me around so I could tune, and damn was I rich! Under 10:1 for air/fuel all over the place. Got it dialed in better and now she pulls a lot stronger:-D As he was driving and I tuned, my brother would go "whoa you're car just got a lot faster at X psi" :-P Anyway, great tool and great price, highly recommended! Thanks for the link Doug.

I LOVE hearing or thinking that while tuning, glad to hear you got it dialed in properly. NOW YOU KNOW WHY NARROWBANDS SUCK MONKEY BALLS, SPREAD THE WORD. ;-)

thats pretty much how me and sam do things. occasionally we'll be safe and tune each other's cars tho, in which case we spend about 20 minutes on the interstate and set things out real fast.
