Yanked the Hondata, and ran Uberdata tonight..
 

Just for the hell of it, I removed my Hondata tonight and ran my car on Uberdata.

B16
T3 60/63
All the normal turbo stuff
86lb injectors
PLX WB

Made a quick base map & turned the boost down to 7-8ish
Car started first try, was a bit lean causing stumbles at idle. Drove like a pile.
After about 15 changes/test drives, the car idles solid, and drives w/ 0 hiccups. (OK, very small ones at parking lot speeds, but very small)
If it wasnt for my broken Romulator this could have been completed in about 2hrs, but took about 3hrs. Tuning part throttle w/o datalogging is MUCH harder, but can be done. (running the car in open loop is a must for this, unplug your O2 sensor and disable O2 Heater in Uberdata) Tuning WOT was pretty easy, just gotta make mental notes on A/F vs RPM vs boost.

Overall, very impressed. FTL is a blast. With my Hondata's (older 2bd) inability to disable ELD, this is the first time I have been CEL'less in a year and a half lol.

Uberdata exibited the same IAT/Fuel correction problems as Hondata did when running vary large injectors. About a full 2.5 A/F swing at idle depending on cold <80 IAT and heat soaked >120 IAT at idle. As long as you make sure you get your IAT's down after a heat soaked start, WOT is barely affected. Hondata also had a problem with overcorrecting for ECT at cold start/warm up, by as much as 3 full A/F points. (newer s200 has adjustments for ECT enrichment)

I will be planning on running both my Hondata and a Uberdata rom at the track very soon. repeatable FTL on slicks is gonna give Uber the edge :)

cool man, i bet the engine management geeks will love to see this. you just run it for the hell of it? are you holding on to your hondata too? i just ordered my obd2-obd1 harness, i can't wait to run uberdata ;D

Re:Yanked the Hondata, and ran Uberdata tonight..
 

nice man. I'm going to be doing the same too with uberdata. I'm gonna wait on my wibeband before I do anything with tuning. I just need to get couple of others parts for my g-ride before I fire her up.

Deff. wait on the WB.
Hell look at it this way, even if your starting from scratch:

Uberdata: Free
Ebay laptop: $200 if that
Burner:$140 at the most
Chips and ----: $30
Paying someone to chip your ECU: $50
WB: $300ish

Total: $720
Not ------- bad, and you 'could' do w/o the laptop and just use your desktop at home. Even chip some stuff for friends and make your money back on the burner/chips.

Even cheaper if someone local has a burner you can use...etc

Yup, even a bit supprised at how almost perfect part throttle is w/ 86lb injectors and no datalogging/map tracing.

cost for me:

conversion harness: $78
450's: $60
socketed obd1 ecu: $75
driving to see j.davis to have him tune/burn a chip for me: priceless!


grand total, $213!! less than a gay ass afc, not to mention, that's including the injectors, with an afc you would spend more and still have to buy injectors and not run half as good! uberdata/turboedit PWN JOO!!!!!!!

looks like I know who to go after once I put in my uberdata

turbo edit is my friend

Re:Yanked the Hondata, and ran Uberdata tonight..
 

Non turbo related question :
Could an incorrect valve adjustment do this? Everyonce in a while my car takes about 10 more cranks than normal to start. when i did the valve adjustment, as far as i can see, everything is in spec.

Is your engine stock? Does it do it when only hot/cold?

Re:Yanked the Hondata, and ran Uberdata tonight..
 

What did you use for a basemap? did you just apply 120% fuel effeciancy and .9 degree/lbs retard?
