Thanks for info. Rather than going thru the maths ( not a big deal for me), wouldnt you just do a straight per centage ratio calculation ie newKINJFLOW = old KINJFLOW(grams/sec) x( new inj ( lbs/hr) / old inj (lbs/hr) ) ??

Ahh .. found it buried in the scaler tables. Any clues as to the LB/hr flow for the standard VNV8 vs VSV6 supercharged injectors ?? Mike

Guys, As mentioned before, I am a little new to Delco tuning , but have heaps of eprom tuning experience with other makes. Friend has a VQ Statesman that I'm building a stroker 383 for. I plan on upgrading to the VS supercharged injectors. I'm using the $5D XDF to read the bin etc. Theres a lot of t...

Sure will need bigger injectors ... especially since I'll be running E85 ethanol. I will be using Siemens 910cc injectors.

Thanks guys, I reckon I can read the rom now. I have a ASBX9285memcal, and I used the $5D def file to read it. The next question is .. if I alter the VE table and the spark table, what effect will this have on the checksum . Is the checksum important for Delco chip writing and how do I correct it ? ...

Guys, I am new to the delco tuning... I have mainly done Mitsubishi and Nissan eprom writing ( with Tuner Pro). I have a friends VNV8 that I have just rebuilt with a stroker kit and 286 Crane Cam. From past experience, I reckon I will have to upsize the injectors. Therefore, I will definitely need t...
