1st Gear Fueling Adjustment

[Mr86t-type]

Guys,

Only thing left that I can't quite figure out, and I'm pretty sure it'll help my 60' and overall ET is 1st Gear Fueling adustment with the TurboTweak Chip, I have my Overall Fueling (with 60# Injectors) set to 138, which is +7.8%. Now when I go to #2 (1st gear fueling) do I start FRESH fom 128 nd go to 133 (ie if I want only +3.9% say) do I simply use 133?? O do I somehow SUBTRACT from the 138 Overall????

Thanks!

Setting #1, WOT Fuel, adjusts fuel for all gears (including 1st). Setting #2 only affects 1st gear. So if you want to make 1st gear leaner, then you would reduce setting #2. Setting #2 is completely independant of #1.

Oh, so when I see 128 at setting 2 (setting 1 being 138) then that 128 is Actually the 138 (Overall), so by Subtracting, going to say 123, I'm actally pulling from the 138 number (subtracting % from)??

If I understand you correctly, yes you would be subtracting from the 138 number for 1st gear only.

AhHa, Cool...thats what I'll Do! Thanks, and BTW on the Idle at 650rpm you set for my 60's..it's 100% PERFECT!! Smooth as silk!! So I'll send you back the 800idle chip...And I'll see if I have any other Blanks for Ya!!

Take care!!

i posted on the magna forum but it should be here as well

setting #1 adjusts WOT fuel (all gears)
if your first gear fueling is fine at base settings (#1 and #2 setting at 128 ) then adding wot fuel will richen all over including 1st gear , so you need to subtract from setting #2 as much as you added to #1 just to be back at base

safe way is add #1 fuel as you slowly bring up boost to your desired level untill your top end fuel is happy , once the top end is sorted out work on the 60', back out # 2 setting seeing how it affects your 60'

start rich and see waht the car likes as you lean it out

in johns case i had set at 145 wot (+14.5% above base since chip was burned for 17psi and he was running 24psi , and im sure eric never meant this chip to go 11.0 with a 3600lb car ) and 112 1st gear (only .85% above base setting as eric meant it to be )
