I just replaced my 7530 ignition that I purchased in Nov 2003 with the 75301 ignition and my timing changed from 36 degrees to 30 degrees.

Is this normal?

I had just figured that these two ignitions would be the same on the timing. I had read elsewhere about there being a slight delay with the digital 7 ignitions. I use a crank trigger and realized that my timing was set statically at 36 so I guess the 7530 or at least the one I had, has no delay like I have read about but this new 75301 does. Maybe it has something to do with the TCD?

Car ran fine with no problems at the track last night. Couldn't say the same about the driver 4th round.

Thanks for all the help,

391T,

All of the units will have some delay normally. It can very some but will normally be 4-8 degrees What might have happened is the unit you did have was on one end of the scale and the other unit is on the other end which would account for the difference in timing. Just make sure that the timing is being set with a none adjustable timing light. This will ensure that the timing is what it should be.

Thanks,
