new injectors (fuel consumption increased)
Hi all, i from russia, need help setting up fuel consumption
i have Celebrity `88 replaced its 2.8(lb6) on 3.1 (lho) ecu - 01227730 (bin arxw) $6d mask tunerpro.
replaced old injectors (Rochester / GM 5235136) 15.22 lbs\hr 160cc 115.0 grams
on new Bosch injectors (0-280-158-110) 15.35 lbs\hr 161.3cc 116.0 grams
I badly write in English. understand and forgive)))
I understand that these injectors are different mechanism. new injectors plastic and wery speed open
while older injectors are slower opening....
the question is what you need to change in the bin to adjust the opening time? and what parameter is responsible for this? which parameter is responsible for dwel time ingectors?

Re: new injectors (fuel consumption increased)
The $6D XDF and ADS are available on the TunerPro website. Will need to at least change this table:
BPW Offset Vs. Battery Voltage
If you don't have the injector compensation data for the new injectors, can use the BLM to change that table. Change the above table to get the BLM mostly in the 128 range. Will need the ADS file in TunerPro RT to get that value. Or a standard scan tool can be used.
Note that he BLM is the long term fuel trim.
