Once i plug in the obd1 w/ uberdata i start car up and it idles for about 10 sec and shuts off. Its flooded. I pull plugs and they're soaked. Ok so i put plugs back in and lower the fpr to about 34 psi. I crank and crank and it doesnt start. So we push start it and again idles for about 30 sec running rich as hell smoking everywhere. i pull plugs again and put new dry ones in. This time i plug in the stock obd2 ecu and it starts right up. Running rich but not as bad... i lower the fpr to about 20 psi and now it runs and idles good. So what could the problem be? I made a base map on uberdata and calculated old injectors with my new 440's. Could it be timing? On the base map i put suggested timing for 9 psi + but i'm currently running on my wg spring which is 5 psi. Could that cause the massive flooding of fuel? Sorry for the long post and if i didnt explain it well... any other ideas would help. Thanks guys. peace

 

why aren't you just lowing your fuel in the maps in UD?

 

What are the #s reading for idle fuel in Uberdata?

Did you enter "440" in the OLD fuel injector size box? Because that would be backwards...

 

Youre supposed to run stock fuel pressure, which I believe is 42. From the basemap, select the entire non boost portion of the map and start pulling fuel, until you get closer to your target A/F ratios. The basemap is supposed to be super rich, so that it is safe starting point.

Yeah i put in the old injector size(240?) and then the 440 in the new and then submit and then both old and new are now set at 440.

I dont really understand what you mean. I'm new to uberdata and tuning. I just want a basemap that'll run good/safe so i dont have to run on my stock ecu.

 

Yeah, just do like alchemist said. My car is far from tuned, but I don't even have a basemap to go off of (accord running of prelude map). Started up initially - running rich. Pull fuel across the board and idled fine. Didn't do much more than that since I didn't have my wideband hooked up, but it shouldn't be that hard. Would help greatly if you have a wideband.

How do i pull Fuel across the board? Explain please I'm noob at this. Thanks.

 

Just click and drag your mouse across all the fields you want to modify. I'd probably select everything under vacuum. You can use the page up/down keys to modify, not sure how much they change it though. You can also use the interpolate buttons.

No offense, but you're playing with your engine's livelyhood and unless you know what you're doing or at least what you're clicking on is doing. I'd be very careful. Also help greatly if you have a wideband. I wouldn't attempt to tune w/o a wideband.

Might help to hang out more in the Uberdata forums too.

I'd try to find someone who knows what they're doing to help you out, if you can.

Basemaps on Uberdata always run very rich from my experience. I've had to take out as much as 30% from a basemap to hit a good 14ish AFR at idle on 550's.

I wouldn't just pull fuel out from the entire vacume portion of the map either. I'd probably go from about 6in/hg back to 24in/hg.

Do you have a wideband?

 

I don't have a wideband right now. No one around here even knows what uberdata is... there's one shop that has a monopoly on tuning hondata but they're no help. I asked them about uberdata and they just said it was **** and i should go with hondata. I'm trying to do this myself. I was hoping i could just run off a basic basemap without a fine tune cause i'm sure thats safer than the stock ecu and a vafc. So i dont want a precise tune right now with datalogging and wideband(even though i'm sure a wideband wouldnt hurt) I'm pretty low on funds at this point and i was hoping just to get a good/decent basemap running that i can feel a little more comfortable driving on instead of my stock ecu. Maybe someone on here can walk me through a little adjusting on the basemap on AIM. But i dont know anyone on here that would do that. Thanks.

Tuning without a wideband is not safe, how will you know what your airfuel rate is?

Have you read the uberdata forums? http://www.ecimulti.org/uberdata/forum/index.php

You should make sure you know what you are doing before you start playing with your tuning.

Even if someone else made a bin for you that had a simillar setup, there is no gaurentee that it will work well on your car. Only one way to know: wideband.

 

I understand what your saying about the w/b. But look how i'm running now... STOCK ECU. How the hell do i know what my a/f is at now? Dont you think I'd be safer running on my uberdata ecu? Even if i didn't know what my a/f is with the uberdata ecu, couldn't i make a safe workable basemap is what i'm trying to say.

Uberdata w/o wideband vs Stock ecu w/o wideband

Whats better? Uberdata i'm assuming. And yes i've read uber's forums

If I were you, I wouldnt even be running the turbo on my car until I had enough funds to get some type of fuel management, (Uberdata, wideband, burner, ect...)

???

I have my fuel management... uberdata. I have everything i need minus the wideband... like burner, chips, etc. All i need is some help with the tuning part. I did uberdata for one main reason... so i can tune myself. But no one seems to want to help.

Hondaguyef thanks for the link

 

I pm'd you. I can make a base map for you and I'll e-mail it to you.

I don't want to be an ***, but whatever you are doing, its not really tuning. You are just "playing" with your car via UD. To tune a car, the minimum you need is the wideband. Others will continue to say you need a dyno too, but we'll just say thats for maximizing power. So without a wideband, how are you going to know if you need to add fuel or remove fuel in certain zones of the fuel map? Is proven the "Butt Dyno" is not accurate and the Butt Dyno definitely does not have a WB feature add-on.

Use your credit card, barrow money from somewhere and buy a WB so you can tune.

As far as your problem sounds, I had no problems creating a basemap for my P72 following BigWigs "How To Make A Base Map" instructions. The base map started up and ran RICH is vacuum and LEAN in BOOST. And I'm not saying by a little bit. It was groosly rich and grossly lean. But the car ran and drove and never died on me. I've search a LOT and read a LOT about UD on H-T and the UD forum BEFORE I chipped my ECU for UD. I've read about someone else who had problems like you. The car would not start, and if it did... it ran rich as hell and then dies. The plugs would get fouled and no matter how much fuel was removed from the UD maps, the same symtoms. His problem was a bad ECU (I cannot remember if it was related to poor "chipping" workmanship). This may be your problem too if you are sure you made the basemap correctly.

Uberdata, on the most part is for the DIY crowd. From reading your post, it doesnt seem like youve spent the time to read and research the basics of Uberdata. You should spend more time researching Uberdata on the uberdata forum, pgmfi forum, keebler65's webpage, importbuilders articles, ect...
