Advice for firest time procharger tuner

[joecar]

The tuning data for my injectors are from HP tuners. If I sent the tuning data that I got for the Fast 65# injectors would someone convert it to EFI Live or show me how to convert it to EFI Live.

pm sent.

Here is the tune.

The procharger is going on on Friday. And going to start tuning that afternoon. And there is a test n tune at the local track I may go to on Saturday. Any advice? Should I start with pulling 20* of timing throughout the boost range? That will make my max timing around 10-11*. Boost will be in the 8-10 psi. Not sure really. It's the stock 4.38" pulley and going to start shifting at 6300 and bump the shift points up throughout the day.
Thanks

Andy, is your FPR manifold-referenced (IFR flat) or un-referenced (IFR sloped)...?

[andysc3]

it will be referenced. and will be 1-1 with boost

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

Your B4001 IFR table needs to be flat (same value in all cells)...

From the FAST 65 data you showed me (as I interpret it):
the pressure delta is 400 kPa (since the FPR reference cancels out MAP above and below the injector) which equals 58 psi;
from the spreadsheet 58 psi is closest to pressure delta 59.2 psi gives 65 lb/hr or 8.19 g/s (calculated from 65*0.126);

[ assuming your measured rail pressure is 58 psi with reference hose temporarily removed ]

correcting to 58 psi: 65*sqrt(58/59.2) = 64.3 lb/hr = 8.10 g/s (64.3*0.126);

so your B4001 IFR table should contain 64.3 lb/hr or 8.10 g/s in all cells.

Thanks. Is there anything else that needs to be changed for the injectors?

[joecar]

The FAST 65 spreadsheet contains the voltage offset table in transposed form, and the axis is in psi and it is in pressure difference rather than vacuum...

so you would have to convert it to vacuum in kPa

(convert axis to kPa, and then subtract each axis label from BARO (101 kPa)

In the FAST 65 spreadsheet the Small Pulse Adder goes into the B4005 Small Pulse Adjust table, but it skips every other cell.
