Tuning '94 chev Suburban Big Block

Nasty-Z:

Thanks very much for the reply as it has cleared up the sense resistor and Memcal mods. Apparently, Ken at HP tuners has the knowledge to impart upon others and this does not affect his present business. I need to go back and review the Memcal mod and how it affects the firing stategy of the injectors. I will jumper the sense resistors to keep the ECU from going into the peak and hold mode. Again, thanks very much for clearing up the understanding of these aspects.

Regards,

Rolly

There are many with a very good working knowledge of the '7427 , Ken was/is one of them . He helped me tremendously. I believe he and I were one of the first to try the PFI mode in the '7427 to work with the shortcomings of the Edelbrock MPFI conversion. Doug Stalter (ECTune on many forums) who worked for Edelbrock basically had his hands tied when the original calibrations were designed in house at Edelbrock for the conversions. This is why workarounds were discovered and it was a good thing they were , the Edelbrock calibrations were bad on a good day .
