lol shouldn't be that popcorn worthy. I just htink it's noteworthy for guys running alt fuels. for those who aren't the difference is minute.
My OB community timing meter idea!

Check here, Gary; http://www.costplustools.com/Kent-Moore-Tools_bymfg_97-0-1.html I see the "harness" is just $107.00, but it shows the probe with it. The probe on the same page is almost 350 bucks ALONE! If they're selling the harness with the probe, we need to grab the harness deal right away!
As for which method is the best, mebbe they should be checked both ways when you time one up, IF somebody has the capability to do that? BUT, if there IS any real difference between the two, would that clear anything up? In fact, if a fella is timing a certain way and the truck performs well, and/or better than it had been, what does it really matter? There are certain "things" that we look for to tell if the truck is performing good, if we see those things, done. But, if you're doing exhibition truck pulling, then timing for every ounce of power becomes all important. Hell, just get my truck running good and I'm for what-ever method is used!

Both the luminosity and the pulse methods require you to take some things on faith. With the luminosity method you have to trust that the hole you're timing is representative of what's going on with the engine as a whole. You also need a general idea of what the fuel's cetane rating is because with luminosity there are different specs for different fuels. If done right it COULD be more accurate than pulse, but it is a pain to get glow plugs out of a hot IDI. The pulse method assumes you can get a good pulse reading and that any difference between fuel types will be insignificant or you already anticipate and adjust for that difference. I've never done the pulse method but it sounds like it wouldn't be as hard as luminosity is. I think it's a great service Gary is offering to the community to rent the Kent-Moore units out. I really wouldn't want to lend my MT1480 out, but I'm always glad to use it and will help anyone who happens to be in the neighborhood or will meet me reasonably close to home. I got really lucky to get what I got. I had a good almost never before used luminosity probe from an older Snapon MT254 lumy adapter that I got for around 100 bucks and bought a useable 1480 meter from another FL member who had no good pulse or lumy probes and sold me the meter at a very reasonable rate.

Heck, I would love to see a state by state list of "shops" who can actually time our engines. At the very least, it would be a good reference for when the truck needs a repair that I can't do myself due to a lack of time/tools/know how/ and or space.
Thanks for the reply's 
Well sounds like I need to plan a trip East. I'm supposed to be be in Findley Lake NY to meet the inlaws at the "cottage" (we call them Cabins out here
) in July maybe I'll take the time off and head there after/before the Rally 
I hate flying with a passion and that would be a fun road trip in the IDI. A second mortgage should cover the fuel 
It would be nice that's for sure. The guy I had do mine used pulse and it seemed to run good but at the time I had mixed injectors (didn't know until after) and I'm sure that made it impossible to set right. Of course the timing went out the window when I installed BB's. I trust the shop to do it right but I really don't want to spend another $150 and find out I'm wrong lol ;p That said the guy's timing work on my 92 Cummins was pure magic--I didn't think any motor with 250+ miles could ever run that good.

In a perfect world, yes lumy might be better. But in the real world, my observations are this... if you stare into a lumy probe window you will see that the intensity and quality of the flashes vary widely. The nature of an optically coupled system and photocell technology commonly used in lumy hook ups is afected by temperature and moisture. The photocell sensing circuit has to measure a wide pulse width and the rising edge of the pulse is the only part that can be of value. Variations in flame pattern and interference from smoke can result in a loss of hysteresis at a critical moment, and you can get a stepped trigger effect. Net net is that lumy readings are far less stable than pulse. With the pulse method, the line swells X amount, and during that swell the capacitance changes from nominal to something else. The capacitance is extremely stable and the line cannot change values more than once per injection event. This produces a much more rythmic and stable pulse than the optical method. However, if you like the lumy method, then more power to you. The important point is that often only one method is available, and a single method is better than no method at all.

I guess I'm being misunderstood. yes, a list of IDI friendly shops would be nice. However the point I was trying to make is lets have people help people. Rather than rent out a tool and risk losing something, a guy could say,"Hey im in Phx, if you need timing call me at (999)666-6666 slide me 50 bucks to help pay for my tool and I will help you adjust timing" I dont know about you guys but I dont like the idea of mailing my tool across the country so some guys can use it for a couple of hours then send it back to me when he get around to it. I would rather meet up with someone, help them then visit a little bit, isnt that what Oilburners about?

I stand against my oponent by saying i am against those things with which he disagrees!
Further more with all due respect to my openent i agree with everything he said!

No, I understood what you meant, and I agree. I was just saying that even if all I has was a list of shops, I would still be thrilled.

I agree a list of shops that are reputable that actually time with the right tools, state by state would be helpful, and so would a list of members with tools willing to time others trucks for free or a nominal fee. This would be a pretty heavy duty research project unless we had a few different people take it on.

Good Morning Ya'll.
Why don't everyone who has a timing tool list it in there signature like I do. Then PM that person for a time, place and cost if any.

Cool, I'll start. I have a working MT1480 and I know how to do luminosity timing, I'll add that to my sig.

Too bad I couldn't find someone in southeast Iowa. I will probably have to find a good shop once I get my truck going. I am considering just getting it close and buying a used meter down the road. I could see where I could use it pretty often.

Is getting worn out
Wish there was someone in TN with one, i would like to know were i have mine set, then put it to spec and see the difference

I have a very unused J-33300-A Kent-Moore machine, with the magnetic probe pickup and fuel line adapter for sale for $400.00, plus actual shipping charge. It's in excellent condition. It looks like the spring clamps that attach to the vehicle battery, (to power the unit), the mag probe and line adapter have never even been connected to a vehicle. Email me if interested.
