Bonneville America Forums Forums Technical Forums Performance Mods Procom CDI Observations

These procom CDI's have been in the field for several months now (Jan 1st, 2010).

Any issues with performance?

Starting the motorcycle when the procom CDI is in place is one, as starting is different/difficult. (till you get accustomed to it)

regarding the base line map

Cinnamon Girl is real flat from 1000 to 2900rpm. Then she kicks butt to an rpm round 5k...dang if she didn't run like she was lean...

Regarding BrianT's timing alternative map: (Having just reinstalled the GILL CDI), acceleration from 4K is noticeably better with the Procom cdi than with the GILL in place. A crisp roaring acceleration. Crisp. yeah a good word that crisp is.

I've got another issue that shall remain nameless for now, thus my query regarding anyone else having issues and if so what it is/they are. The GILL CDI is back in place on Cinnamon Girl for now. Without having the service records in front of me but having access to my dated fuel records, my estimate is Cinnamon Girl ran about 1700 miles on the procom CDI.

Yoe, Moe, can you do infinite programming on these CDIs or are you limited to just the few maps already available. I mean, can you laplink to it and play with it through some sort of other software such as tuneboy or the others? Do these have a graphical display of the tuning you can do? If so, I'd like to play around with one as I am pretty litarit on kumpoters. Seriously though, can you do these things?

infinite programming re both the throttle position and the timing advance vis-a-vis rpms solamente. Or rather within a range. I suppose you could input negative numbers. Remember the maps are created from procom's baseline.

Don't know about accessing it with a tuneboy or the others as I don't have access to any of those. But for the throttle bodies rides can't you tune those maps using dynojets etc right now? The stealerships can.

When I get my procom cdi sorted I'll let you borrow it.

today tested default map.....not happy
Procom map number 9 was ok more testing to come

Now running map No:9 TPS connected with PVL coils and this baby roars..

have no tps....not even place to connect it but something tells me that on map 9 had better acceleration

Did you try to build Your own map?

How hard is it to install a new map

few clicks and you are done

The software say's windows 2000 or later excluding windows vista does that mean I cant use windows vista?

you can use Vista I'm using it and no problem

ok thanks

I just CAN'T have TPS and on map 9 bike was running perfect....just this starting issue

No help to you but my bike is starting like a champ now, I just pull the choke and hit the button, dont touch anything else and its instant start

I do plan on trying with the TPS diconnected again... curiousity and all that

I put my own map today and it started without problem but will be trying it more with different set up

My observations looking at the latest Procom maps are, procom have not altered the timing until 2k RPM... I believe before that the ignition timing was being advanced earlier (even at startup speed) which caused the poor starting.

Make sure you post screen grabs of your maps and maybe even the file, youll feel all warm sharing..

I'm having serious issues with the procom CDI. When I first installed it, my bike did great. Then it started dying at stops. It would restart just fine and run. Then it started running rough. I reinstalled my OEM. Later I mounted my procom in a position to switch between OEM and procom. Reconnected procom and the bike ran good for about a minute then it started cutting up, backfiring like the plug wires were reversed and would go dead. It would restart fine then after about 30 seconds the same thing. I contacted procom and they exchanged it no problem. The exchange came and I connected it. The bike would start and idle no problem. After about 30 seconds it would die. It would restart and idle again with no problem and after about 30 seconds, die. Then it would run on only one cylinder. I reconnected the OEM CDI and it runs with no issues. I've set the dial on the procomm CDI to position 5 to match my OEM CDI number. What other settings are you Speedmaster and America owners using? Do you have any suggestions how I might resolve this issue. Otherwise I'm sending mine back for a refund. Thanks. HD

Check your voltage someone said that the procom's don't like low voltage

Is that at the battery on on the wiring harness going to the CDI?

Not sure I think its just overall voltage for the bike. Check your battery voltage.

I removed the procom CDI Tuesday morning April 13th, and re-installed the GILL CDI. Why? Dang if I didn't have a shut down issue on idle when hot, then a stumble issue off idle when 50+ continuous miles are on the clock. All the symptoms of a coil going south. I tried two other coils off a used 07 speedmaster (6 combinations given one of the 07 coils might have been bad, can you say lot's of tank pulls?) , new spark plugs, other spark plug wires. All that was left was to reinstall the GILL unit.

The Gill has been zapping away for 294 trouble free miles now.

So I have ruled out ignition coils, wires, spark plugs. What is left? Could the gap be the gulf?

I'll be on the phone with Wesley after the GA Rally about the problem that was the impetuous of this thread.

NOTES:

I had 1497 miles on the procom CDI when I pulled it off. My daily commute is 10 miles each way. Cinnamon Girl would shut off at idle at least once on the way to/from work.

Jan 31 2010 is when the Procom CDI was installed.

March 12, 2010 I received the used 07 speedy coils and wires for trouble shooting. Therefore without having documented the exact date the first idle shutdown occurred (as I would have bet $100 it was a coil) it must have been at least two to three weeks earlier.

I pm’ed TrOjAn (Terry) about the issue March 4th. So it seems that the Procom CDI operated normally for neigh on 1 month.

Whats a GILL CDI? How much does it cost?

Gotcha on the Gill. Thought you might be referring to another aftermarket product. I always refer to that as OEM. I've got 34kmiles on my bike with no issues with the OEM CDI. I've been running Nology hot coils and wires for over 20Kmiles with no issues. The first Procom I got ran good at first but was hard to start without boosting the batt. Of course that was back in January and pretty cold even for the south. Otherwise, once going it did great. I was amazed at the difference in performance even with stock pipes and carb configuration. I'm running open pipes now with 126 jets in my carbs. Speedmaster 865 carbs on an America 790. Does good but that Procom unit makes her run like a red ape. Sure would like to get one that would work right. Don't like pulling the tank every time I turn around either. The replacement unit that Procom sent looks shotty in its assembly. The pins where the wiring harness connects are all out of line and the plastic shell is uneven across the back edge where the Scotch Cast is poured in. I think they must have good design and circuitry but the manugacture process lacks quality control. I've not abandoned the idea yet. I'll check some things like voltage and so forth, and see what I can figure out. I was wondering what dial setting the other 270 degree engines were using. Mine is set to 5 for my OEM part number but I'm wondering what makes the difference? What settinga are the other Speedmaster and America riders using? What is different electrically on the Speedmasters and Americas that causes Triumph to use different CDIs on the different models. I know the 790s have different cams and there are slight differences with the carb configurations but what about the electrics related to the ignition system? I just don't see that there is that much difference in the actual parts. Timing/maps yes but the parts like coils, wires, pickups, fps etc. Just don't see a difference. What do you guys think?

Triumph corporate is very hush hush about the CDIs. Go figure. If we knew why different model CDIs were spec'd we would know the hush hush. What ever the hush hush is, it appears to be so ridiculous that the gag order on divulging the hush hush, is to some, nauseating.

Have you verified the pick-up coil gap, said pick-up coil residing under your right engine cover? To me that is the only variable left.

btw, my itty bitty blue dial is set to position '4'.

Groovy baby yeah! Thats what I want to know. I noticed that my tach jumps with the Procom. It jumps a little with the OEM. I got it off a salvage speedy at pinwall. I'm gonna hook the Procom back up and do some chekin that will include diconnecting the tach. But I know some other folks have got to be having some issues too. Lets air it out and share it with Procom and maybe they'll produce a descent product that we can rely on as a viable replacement for the OEM. They seem to be socialble people so far. I hope I can get my issues worked out. The gap of the pickup is the only thing that I haven't had my hands on. Heck, 34000+ miles, including a deer strike and recovery, and it just keeps going and going all day long. I've had no reason to check the pickup gap.... other than curiosity. I'll order a gasket and see.

just to avoid confusion Cinnamon girl is a prefire and redundantly, a 790cc.

I would want to try my procom CDi on someone's bike that has ensured their pick-up gap is set to 0.8mm. and that has the appropriate oem part number so the unit remains on setting '4'.

Once again, I must plead ignorant as charged. I don't know what you mean by pre-fire. 790, 270, 360 are terms I understand when used in the context of displacement and ignition. But prefire, I don't understand what you mean. Must have something to do with ignition but a duh... I don't know what duh that means duh.....

Once again context is king! LOL Now I really feel like D A. Is your Cinnamin girl a Speedy or a BA?

Bonneville America

Has there been an update or consensus on the Procom CDI yet? I have a friend whose stock CDI is failing at 15k miles and wondered whether to look for a Gill or get the Procom. After reading this thread, it sounds like there may be problems with the Procom units?

I got set of 10 new maps from procom to try them out

I've had no problems either......my only issue is that for all of my computer life, I've had macs and I have not yet been able to get my hands on a pc laptop to try other maps....the default map used by procom seems to have less spark advance at low to low-mid rpm's and I'm sure some of the other maps will improve this......and I did have to replace my original (03) battery...the triumph cdi didn't seem to care if voltage was a bit low, but the procom did.....I really don't consider these to be problems.....

I put about 150 miles on the bike today and this was the first time it's ever had regular gas.....I actually think it's running better with regular than high test....once I've driven a few hundred thousand miles, this procom igniter will have paid for itself...

So I'm thinking about buying one of these bad boys. My coils are fine, but I'm looking for a little more performance. I'm not too up on this end of the bikes. I got spectres, no TPS, rejet and no airbox with K&Ns. This worth the money even though I'm having no issues? My bike rips as is but I of course would like more. So whats the deal? Its an 08 speedy btw.
