Siemen deka 60lb injector issues need help

[jdf-383]

Hey Guys,
First time doing an injector change tune, have tried getting my tune up spot on but car keeps flooding itself at idle and wot, have only modified ifr table and just multiplied my old table by 2.31 as my standard injectors are 26lb have a v2 vortech charger, does anyone have a tune with the injectors specs or any help would be grouse, thanks

Just changing the IFR table by some "calculated number" will not work. You need the correct injector data. The IFR tables, Injector offset, SPA and Min PW tables need to be correct.

Here are Ford data. You can covert it from there. but Ford use 40PSI Fuel pressure...

You will need to convert the Ford data to GM and your 58 psi fuel pressure or get Greg Banishes first DVD which has a injector data cd and the Siemens 60 is included.

Hey geniuses, let's check part number first lol. There are a few different "60lb" Siemens injectors out there. The ones ones the Banish DVD are actually ~63lb at 3 bar.

He asked a question, he got an answer based on his detail.....and not to split hairs but the injectors in Banishes CD are :generically" known as Siemen Deka 60's....not Siemen Deka 63"s! And lastly regardless if he cant find GM data then he his going to have to convert using the converter above as well.

And thanks for the nice opening LOL

There's seriously smart guys on this board.

One of my biggest pet peeves are things like the 63lb injectors being called SD60s. There's several injectors from SD/Continental that flow ~60lb.

So OP what's the part number? That will let us help you get on the right track.
