Does anyone have any idea why GM built the cranking spark chart in the manner shown below? Note the rather significant changes once the engine reaches 212 degrees and the 100 to 450 RPM range? This is the stock table from the GM LS3/480 ECU.

Tom while I haven’t used it often since the car stays hooked up to trickle charger mostly, the times I did pull the plug I did not notice any driving or startup differences from a memory loss. What gets saved?

I designed a master cutoff whose primary purpose is two fold 1. To cut power to the electronics that drain the battery when not plugged into a trickle charger 2. Anti theft. There is a knob in the cockpit that you have to know it’s location and purpose to gain master power to activate all the...

Just sharing here. I tried a very inexpensive method to change the appearance of the wheels. I use vinyl wrap to highlight the spokes. Now I used a subtle color, but your imagination can go wild. Peel the wrap and lay it down around the outside of the clean rim. Remove wrinkles but don't...

Well good news today…..she lives!!!! Last part came in today, finally and pushed the button. Started back up like nothing was wrong. after additional investigation, I suspect the heat blanket played the critical role in causing the hot battery solenoid wire to ground itself to the hot wire...

Thanks Randy, but no secondary solenoid, standard/typical install. It worked for countless starts before this incident. This diagram does answer a question I had, that if one used a secondary solenoid (not sure the advantage) running a wire from the "I" post on the secondary solenoid to the...

It’s possible. After a start and after about 1/4 mile I noticed a noise I have never heard. Shortly thereafter engine died and a puff of smoke exited rear bonnet. Post mortem discovery was exploded starter. Probably caused by starter remaining engaged. $64000 question is why. I think a heat...

Lets see if I can beat a dead horse....no a dead starter. Got some excellent advise on what to check for and I thought this bit of info may help those who have yet to install the starter. I discovered that the even with the same part number, the Bendix gear is cut different. The inside...

Howard mentioned placing another solenoid in the starter circuit. I am using the Infinity system, so I drew myself the diagram below. My question is how to connect the 12V+ "exciter" voltage from the Infinity system to activate the added solenoid AND the solenoid on the starter itself. The...

Is the framing holding your box something you added? Nice job. Share picture of the bonnet connection.

Ill send picture as soon as it arrives. You can verify the parts. Thanks

Howard: Yes it’s steel. Interesting on adding second solenoid. I wouldn’t think having the infinity system would have any impact on that wiring pattern by sending the solenoid start signal to the second relay then from second relay to the starter. I suspected something as you described but...

Neil: No evidence of ring gear or flywheel damage. It looks like the damage was contained. ken: thanks. Sometimes it’s good to be lucky Joel: I ordered the connector, the wire, pin and the rubber insert. I did not see a boot. It’s not that much money. If you found exactly what you need...

Joel - I just ordered the plug that fits yours. I won’t be able to use it. Interested. I have to look up your part number. It appears the 17755N unit is used on the VW 1.9 Diesel. I looks exactly the same as the unit I have. I wonder if the internals differ for differing applications...

I received the new starter today from REMY remanufacturing and I called them to confirm its their rebuild. So thinks for the heads up Neil. The part number I have is 02Z911023L. The confusion I now have is the application. Apparently it fits the Audi R8 2008-2015 4.2 and 5.2, the Lambo...

I was posting on the Graz Starter post in the other area, but felt this merits its own special post. Many have expressed issues with the Bosch starter for the Graz, and like many, I have checked the aftermarket for a better starter that would fit the Graz......no one makes one. Last Sunday I...

Good thoughts Neil. I’m going to take it apart today and see if it’s an obvious breakdown. I just took my ohm meter and ran a continuity check across that wire and the pos terminal of the solenoid and did not get any reading. I then touched the leads to the wire and the motor housing and the...

Heat wrap was on it. Got to check the button......not sure what quality it is. Probably best to upgrade it. Looks nice but......

I concur. The car was making an odd noise when I left the lot. Drove about a mile then it all shut down. I wonder if the starter clutch failed to release and that is what I was hearing. I want to hook it up to a battery and see if it will spin..... I assume no one has found a reduction gear...

I'm bringing this one back from the dead file. There I was going home minding my own business at a stop light, looking cool and all, when the engine dies and smoke puffs out from under the bonnet. I get some help and we push the car into a parking lot, call my wife to bring the trailer and we...
