Hi Guys,

I know that these injectors are crap but I have these ones.

I'm confused with Siemens DEKA 630cc voltage offset. I parsed many forums and sites but I didn't find precise answer for my question - what voltage offset I should use for these injectors. According to URL http://injector-rehab.com/shop/lag.html and according to datasheet from siemesdeka site http://siemensdeka.com/specsheets/FI114961cs.jpg there are difference voltage offset.

Could someone share with me what voltage offset use for these injectors?

Thanks in advance!

Download the nefmoto stage 3 base file, and use that as a starting point. Then, adjust TVUB until idle trims are close to zero (should be good with the nefmoto values).

I used these values. http://nefariousmotorsports.com/forum/index.php?topic=1834.msg17780#msg17780

They seem to work pretty well. Idle LTFTs are ~-2%

Unfortunately deka to deka may have big differences and you have to fine tune many times to calibrate at the optimal point.
Important is to never mix injectors from different batches where problems could be even bigger and so the time and effort needed for proper tuning/calibration.
