ignition upgrades for people w/ too much spare time. Posted by michael [Email] ![]() ![]() |
Hi,
Brad and I recently came accros this website: http://www.max-boost.co.uk
Under the ignition section there is a modification for the rotor involving removing the resistor and soldering a piece of wire in there to remove the 1K ohms of resistance.
We did as the instructions state and rechecked the resistance, which was now at zero. As a side note the rotor we used was a new one. I installed the rotor in my car and found that the car was more responsive, but i immediately had detenation that I didn't have before. So I got curious and decided to do some tests, here are my results.
STOCK ROTOR MODIFIED ROTOR
23 deg. of intial timing 24 DEG. OF INITIAL TIMING
8 deg. of timing under full boost 9 DEG. OF TIMING UNDER BOOST
I am assuming that since it made 1 deg. of difference at idle the effect is greater at higher rpm. So seeing this we decided to check things further.
