So I’ve been searching and reading about voltage offsets for hours now and just about give up.

I have a 91 Silvia SR20DET, and installed Tomei 555cc side mount injectors bought from Enjuku. https://www.enjukuracing.com/product...et-ka24de.html

I can’t seem to find a voltage offset chart for them for my MAP tune. The only info I’ve found is the .71msec bit. (Found on TomeiUSA.com)

Does anyone know where I can find the VOLTAGE OFFSET CHART for say 8-16vdc?

Nearest chart I found was here: http://forums.haltech.com/download/file.php?id=251, but it doesn’t spec the 555’s.

Also read they are Nippon Denso / Bosch just rebranded.

The car idles poorly on cold start and stalls out. Can anyone help with hard data or links?

I’m in for like $10 grand on this turbo & tune upgrade project and it sucks to be stuck at the tuning stage just missing some numbers.

Supporting mods are:
T28 Turbo (S15 spec R)
Walbro 255 fuel pump
ISR FPR
Tomei 555cc injectors
CX Racing FMIC
HKS ssqv BOV
AEM wideband
Hallman manual Boost controller
Apexi boost gauge
ProEFI 48 ECU
ProEFI color display
MAP sensor
Air temp sensor
Fuel pressure sensor

My shop says I need the primary offset, battery voltage offset, and voltage dead time to properly program the ECU.

I’ve reached out to Enjuku, who reached out to Tomei, but haven’t heard back from them as of yet.

Thanks guys.
