Advice for firest time procharger tuner

[joecar]

In the FAST 65 spreadsheet the Minimum Injector Pulsewidth goes into B4003 Minimum Injector Pulsewidth, but again the axis doesn't line up.

( that FAST spreadsheet is hard to use )

make B3616 PE Enable a little easier to trigger PE (set it to 60% below 4000 and 30% above 4000);

make the 0-3200 rows of B3647 the same as 3600 and up (i.e. copy/paste lower part to upper part);
and then make B3618 the same as the 100kPa column of B3647.

Fix the out-of-range cells in A0009, A0012, A0013

[ A0009: reduce the ve value; A0012,13: set it to max-1 ]

B5913/B5914 HO/LO Spark Timing tables will need to be reduced.

For A0010, Boost timing table, Where does it subtract the timing from. When I look at the high octane timing table it goes to 1.20 Grams/Cylinder. Right now Im at about .85 g/cyl. With boost wont that take me past that point? And since the procharger makes boost with RPMs do I want A0010 to be about the same # across the board? Im currently running 31* max at my shift point, if I set it to 20 that will make my final timing 31, correct? and I am running 22* at the lowest so that would be 2*. Does that sound right? Thanks for the help

A0010 subtracts from whatever the PCM computes as spark timing...

when MAP goes above 105 kPa, when 1.20 g/cyl is exceeded, the PCM uses the timing value from that final column (1.20 g/cyl), and A0010 then subtract from that value.

As MAP increases above 105 kPa my understanding is you want to subtract more timing.

OK, I set the PE to trigger a little earlier than what you suggested. The 3700 rpm torque converter is rather loose and Im at about 3k rpm just to keep up with traffic. I adjusted 3647 and 3618. What is a safe AFR for boost. Its set to 10.5 for now. How much do I need to reduce the timing tables? As for the injector data. Its a good thing I have the next two days off work lol.

[joecar]

For significant load at boost you would have to get the AFR to something like 11.4-11.8 or so...

10.5 seems too rich to me, but let's get more opinions.

[andysc3]

OK, Id rather have it alittle rich at first vs too lean and melt a piston lol. For the missing values in B4005, can I avg the cells on each side and put it there? And the same for B4003?

[andysc3]

as far as A0009 being out of range, all the cells are in range so Im not sure why thats coming up.
