37# Racetronix Offset

[Arcolog]

Hey guys,

I've been looking all over the place on here and on LS1 Tech for a solid offset table for the 37# Racetronix injectors (the newer ones)

If anyone has one they can post up, or just link your tune for me that would be AWESOME. I'm sick of staring at these injectors on my desk and I need to get them in and tuned up asap.

Thanks if you can help, and thanks if you can't!

Hi,

Can you please help with ofset table? have you got it ?

Thanks

Nobody has this info, period. You'll need a flow bench that can vary the voltage going to the injectors to get this data.

Thanks, But what difference will it make?

Thanks, But what difference will it make?

ALL of the injector parameters (Offset vs. Volts vs. MAP, Flow Rate vs. Press (IFR), Short Pulse Limit, Short Pulse Adder, and Min Injector Pulse) have to be accounted for, period. If you're not using ALL of the correct values, there isn't anyway that the control of the injector is completely stable. Furthermore, without the proper values, you'll be fudging/lying to the MAF and/or VE (depending if you're running the hybrid mode or pure MAF mode), which will throw off all calculated aircharge, which is very important for the proper functioning of the vehicle.

It's time all of you who are buying aftermarket injectors to start going with ones that we actually have data for (or will be getting shortly with Greg Banish's [eficalibrator on here] training DVD). Quit blindly buying stuff without doing your homework.

It's clear enough for me now. If we cannot get the values, Manufacturers should do it for us. I mean why they sell a product that cannot be correctly used.

I will be running pure maf tune after setting up the VE table in case there is an issue with maf in someday.

What challenges will I face?


Thanks for your time

I searched all over the web for this before ultimately getting it from the ACCEL. The number on this document does not match the number on my injector, but ACCEL tech support assured me this is the correct data for 01D114B injectors.

The PDF is 210kb but this forum limits uploads to 195kb. Therefore, I've created a JPG of this in case ACCEL breaks the URL above.

The file conversion resulted in difficult to read Offset vs. Volts data, so I've typed it below for clarity.

Voltage Time Offset (ms)
6 4.009
8 1.878
10 1.260
11 1.103
12 0.950
