Fast 36 lb injector Bocsh? Specs for calibration?

[EagleMark]

I think these Fast 36 lb injectors are Bosch as the numbers are 0 280 155 868 which match.

Is the correct injector information available anywhere for the LS1b PCM ?

I have it in hpt format, site will not allow me to upload.

How Rude!!! :laugh:

What's the extension and size needed?

[mecanicman]

.hpt as in hp tuner file and 512kb

See if that works?

Will I be able to open that with the HP Tuner trail? Haven't used it much, I've got the other 2 brands...

If I can get that injector info into the LS1b PCM all I need is MAF starter cal from 2008 6.2L Corvette. Should be close and make it run to tune! :jfj:

You can view with trial hptuners. If it does not work out let me know and Ill copy and paste into text.

Here is what I used. I think these injectors are similar to the 3800 supercharged injectors from late 90's early 2000's. ?? I know the number is different, but at the time, that was only place I could get data, so I pulled data from v6 supercharged ecm files and made it work in ls pcm. Here is what I had. I ran an engine on dyno with these numbers and seemed to work okay. Fuel pressure at 58 psi, vacuum referenced, so these are about 42lb at 4 bar. The injectors I had in the engine were brand new from FAST, advertised at 36 lb injectors.

Attached is a zip file containing an export from TunerCAT OBD2 for the 5 tables relating to fuel injectors.

Thanks guys! :thumbsup:

I also found the 36 LB Bosch injectors were used on the 1998 ASA Corvette Ls1a PCM and 2000 ASA Corvette LS1b PCM and thanks to Mr Prick on EFI Live forum had txt as well so I'll post all that up as well so we have all ends covered here in one thread!

I think I need to adjust Injector Flow Rate in EFI Live B4001? Useing the data from the 2000 Corvette calibration above this table varies, indicating a Vacuum Refereced Regulator. The regulator on this engine is fixed at 56 PSI actual reading. So would I figure IFR at 56 PSI and enter here as flat in the table?

Think I had that backwards, a returnless system needs to be sloped but a vacuum reference system does not.

Correct.
