New injectors and tach don't work, old injectors at 164%duty cycle?
So, here's my setup:
1.6 with the standard greddy kit
front mount intercooler
FM dual feed rail
stock fuel system
Here's the problem I'm having with this setup. I took a datalog today and at ~5.5 psi, I'm at 89.9 dutycycle1 and 164.3 dutycycle2. What is dutycycle2?
Anyways, on to the more pressing matters. I recently bought a set of 550 low-impedance injectors with some 10ohm/10watt resistors that I soldered inline. Anyways, I tried jacking around with the opening pulse width that I adjusted via megasquirt's instructions. I couldn't get it to start at all.
Long story short, I putz'd around for about an hour and a half and didn't get anywhere except pissing off the neighbors. I put the 305's back in and loaded up the old map and voila, it started right up ... but the tach didn't work. Any ideas on that?
Thanks for the help!
