Here we go. This is the table I used for MANY a hot (90-95F) day at about 25psi in FL with 56mm turbo. I can't take credit for making this. I just left it as is because it was working well. Also used in conjunction with a base timing map from Marc (no dyno time).

Edit, see my revised table and the table that Chris posted. I can also post my timing table, I have it somewhere.

Do what I did and just get the same sensor they use have VEMS decode it... GM Part #13577394 (Cheap) ... Frequency Output determine E content , amplitude determine temp. Though I don't measure temp.
Description Calibration Conversion Formula
Ethanol Content
(%)
50 Hertz = 0% ethanol
150 Hertz = 100% ethanol
ethanol % = [ Frequency (Hz) - 50 ]
Fuel Temperature
(degC)
1millisecond pulsewidth = -40
degC
5milliseconds pulsewidth = 125
degC
degC = [ 41.25 * Pulsewidth (ms) ] - 81.2

I did that cheap enough as well... albeit with another sensor

Got a link or other information about that sensor? The fitting you put into too, if possible.
TIA.

I think I will have to modify something on my VEMS ECU. I don't have a PS2 input. PS2 does not plug into the ECs, right?
