4" intake piping - 95MM MAF Tuning

[The1]

Thanks for that VL I hadn't looked or have info for past 5000, I will add that when I get a chance and test it, might tomorrow depending on the misses. :p

Hi VL tried that area 6000-60DE but didn't make any change to either CTS or IAT

[VL400]

Hmmm, the numbers seem to make sense at those areas. The table is meant to define what A/D value is for -40 all the way to 151 deg and looks to do that in stock form, it should also be what is in the data stream. What did you change the table to for testing it?

[The1]

here's mine, tried adjusting up and down 5, 10 whole table, did power cycle and all.

[The1]

that's the 6000 table above, also tried the 6011 table and then 6023, yeh they definatly look like it, hmm

[The1]

checked them all trans temp, coolant temp, iat temp, doesn't seem to affect any of them, maybe it's a temp reference tables for other tables?

[VL400]

Are you using the flashtool or TP to update it? The write cal is limited to 5FFF so its a burn via programmer only. Tested it and it does work

Also, the A/D is inverted so the correct table is..

[The1]

Forgive my dumbness yes that works so it seems this is

6000 is IAT Cal
6011 is CTS Cal
6023 is Trans Temp Cal
??
i offset the IAT table by 10 obviously -40 wont go any lower but i think id have other issues at that intake temp

[VL400]

I also may have tried doing a write cal first

6000 = IAT
6011 = CTS with 4k pull up (Cold engine)
6022 = CTS with 348ohm pull up and also trans temp - same sensor characteristics and pullup (hot engine)

The pullup resistor changes as the engine warms up, it gives better accuracy through a wide range of temps.

Some other tables around there are
6033 = Cyl # vs Inj # mapping
6039 = IAC stepper motor state mapping

cool, thanks again for sharing, i will check the variation between the 2 at different temps to see if it's still around 10~ deg c margin, idealy i guess it would be best to control the intake temp and have a accurate thermometer to reference against, but anyway.
