Its me again, are there any maps, or settings to put my Xede at when I run the Methanol? since I wont be able to make it to Dyno4mance. Or do I just hook it up, and "street-tune" it until I can get the car on a dyno? Is there a way to set/add variables to the tables to make it run "close" before I dyno?

I have 100% VP Methanol in the resivoir now.
give the bro a hand!

pull ATLEAST 5 points of fuel from every cell(except the zero ones) on the fuel table for starters.

and secondly, go to call 1-866-548-4GSC and pick up an Innovate LM-1 wideband so you can tune very accurately and log A/F. Ask for greg, tell him Jeff said to give you a good deal. Best purchase ive made to date!

use lambda, not afr. gas burns 14.7:1afr, methanol 6.5:1afr.

While that's good advice, I'm sure that smoked is already well aware of the importance of a wideband.

Smoked:

Did you want something like this: https://www.evolutionm.net/forums/sh...d.php?t=135901
or are you looking for a more indepth meth + smart walkthough?

Thanks donour, and Jeff, this is exactly the info I am looking for. Thanks a mil. Also, I have an AEM UEGO guage on my dash, will this work as a wideband A/F sensor? it has the o2 sensor with it, and it reads "real-time" thanks for the help!

Yeah, that's pretty much what you want. Make sure it's accurate though. As I recall, you like to run leaded fuel on occasion. Remember that it likes to foul 02 sensors.

You probably want to talk to shiv, andrew, or somebody about what UEGO readings you should target for your application.

Will do! Thanks again!

not to hijack the thread, but tell me more about this leaded fouling o2 sensors. I have an xede, just waiting for the cash to purchase smart prior to installing. I also have the innovate wideband with gauge that I have not installed yet. I run 9gal 93 and 3gal 110 leaded at every fillup as my dynoflash is tuned for 96 octane. will this mixing harm the o2 in the innovate?
what to do on raceday when I fill up with primarily 110leaded(about 7 time a year and 4-5 runs on the track and then back to 96)?
I had planned on going back to 93 out of the pump once the xede is installed but what will the occasional tank of leaded/unleaded mixed to ?

thanks for the help

I'm no expert, nor am I the right person to really ask, but I'll take a swing at this one.

Most of the wideband controllers I've seen have pretty bold warnings in their manuals to not use them with leaded gas or use them without properly heating the sensor. Leaded fuel also damages cats (exhaust parts, not felines).

That being said, most folks (vishnu included) claim that it's ok to run the sensor for short periods on leaded gas.

FWIW: innovate doesn't actually make the sensor. They make the controller for the sensor. The senors is made by bosch (which also makes sensor for lots of other people).

yea, I knew about the cats(debatable about leaded fuels and felines at this point )and with o2 sensors in the $100 neighborhood, replacing one every year or so wouldn't be bad, but I also figured that once smart has tuned the system, you wouldn't have as great a need for the wideband once you had a street and a racegas tune. I am not condoning removing it, but theoretically once the car is tuned, wouldn't smart make the necessary adjustments and the wideband wouldn't be needed or does smart rely on the o2 sensor as well?
would be interested to see vishnu's definition of "short periods" of leaded fuels.
that could be a tank a month or 3-4 gallons a year....

(btw, thanks for the response donour. I have followed the vishnu posts for about a month prior to purchasing the xede and I think that you will be providing many answers in the upcoming months. when I get back to see my mum in abq, hope to meet up with a few of the members on the forum..)

Looks like I am in trouble, as I used to run 110 LEADED all the time, no mixture, just strait 110 Leaded for........................30K miles, all with the UEGO guage. the O2 sensor was welded in, right next to the rear 02 sensor. What are the signs it is not working? I had it on Dyno4mances dyno 1500 miles ago and the guage matched up with their equipment, so it must still be OK, right? havent run race gas in 3 or 4 K miles now.

That isn't how smart works. SMART fuel uses the wideband reading to continuously trim fuel levels along a curve you (well shiv) specifies. It's basically like having a special closed loop mode for high load situations. If you have no wideband, then you have to disable SMART fuel.

As would I, although contacting the wideband controller manufacturer directly might be better.

No problem.

If it's matching up to one thats known to be ok, then it's probably fine I guess. I was under the impression that they don't just "go bad". Instead they gradually start reading lean.

d

ok good, when I stomp on it, the guage goes from 15ishg, back down to the low 12's

If i were you(not trying to spend your money) i would sell the UEGO and get something with logging capabilities. It will help you immensly.

Im not sure about the alkycontrol kit, but what i did was set the alky to start spraying at ~14psi and be at full blast at ~22psi. I then started to pull fuel out on the xede until i got my AFRs back down to around 11:1-11.5:1.
