I can say for a fact that the sensor is fine with ethanol, methanol, toluene and xylene. I've used all of those in various turbo applications. The key with meth injection is to choose between using it as knock deterent or afuel source.

Here's a quick reference for stoich:





Gasoline
14.7: 1
6.8%

Natural Gas
17.2: 1
5.8%

Propane (LP)
15.5: 1
6.45%

Ethanol
9: 1
11.1%

Methanol
6.4: 1
15.6%

Hydrogen
34: 1
2.9%

Diesel
14.6: 1
6.8%

I believe AEM makes a good wideband kit, i think its around 250, has the o2's and the gauge. Its a 6-in-1 deal. Looks like a nice unit.

and as for the wide band... yes it is very important! go ahead and mod your car and not pay attention to your A/F...

Thought the gas ratio was closer to 13:1, ohh well could be wrong

For a complete burn its 14.7. Are you referring to power production or stoich? Power production is much richer then 14.7.

thats true that meth has a different stoich afr but remember, when tuning your car to run meth injection on a pump gas motor, you still tune for gas stoich. on a boosted motor running meth you want about 11.7:1 or 11.5:1 afr. i ran mine at 12:1 for a long time with no issues.

if the motor was running on nothing but methanol, then youd run a completely different afr.
