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
