Default TC88A EEPROM or FLASH

Just had my bike done with a 1275 Hammer kit by a great bloke in the UK, Alex at FastLane headworks. Superb job, under pressure from me to get the bike done before I had to get on the boat to go back home.

All running fine and I do not want to tinker with the settings on the TC88A ..but I'd like to be straight in my mind as to what I have got set up.

So this is a question for people experienced with using the TC88A PC Link program. I could ask Alex again, but he is busy with lots of jobs and does not need the hassle of answering any more of my questions

When you connect to the bike and do a 'Download From EEPROM' what will show when you look at the Edit Module Parameters Options?

If the TC88A is already set to use the default FLASH Advance Tables, will that show in the Options tab when you look.

Alex says he used the FLASH tables and used the dials but when I do the EEPROM download the Options page shows the Selection Dot set to the EEPROM Advance table.

So I was wondering if the PC Link software reads what the device is set to (EEPROM or FLASH) ..or if it just sets it and cannot read it.


This below was my last run on the dyno

Just curious... why 9 & 9 ???

Hammer states very clearly to set it at 2 & 0.

9 & 9 because that was what gave the best performance on the dyno, each click produced and extra HP or so.

But I did wonder

Alex does speak to Dan at Hammer and did ask him if he had any maps, but Dan said no they don't, they just put it on the dyno and keep go up a click at a time to get peak performance.

But could the small increase he was seeing on the Dyno, just be as the bike warmed up?

This is why my question about does the PC link software indicate the TC88A is set on Flash or EEPROM, does the software only send the command to change from FLASH to EEPROM, or can it read what it is set on when the "Download from EEPROM ' command is issued.

It could be the bike is still running on the Rico map, the one I uploaded when I did my original 1200 V-Twin Crapufacturing kit a few years ago. (Crap because the barrel leaked oil from the return drilling from the rocker box down to the sump. New kit leaked from new but V-Twin Crapufacturing would not help as I was not original purchaser, even though I had the original receipts)

Trying to understand stuff in relation to the TC88A


With EEPROM set, does the Initial Dial adjust anything ..or are they BOTH disabled when EEPROM is set?

Initial 5 would run the map as written with 4 subtracting 1° thru out and 6 adding 1° and so on unless the map is written otherwise.

Also something to keep in mind. Timing for a wide open dyno run isn't necessarily the best timing for a street bike. 9/9 seems pretty agressive for a 1275 with 10.3:1

That is iiIF the dials have any effect at all when the module is set to EEPROM mode.


I have an e-mail here from David at Daytona saying

Quote:
Neil, you have the most up to date firmware. If you have put a custom timing table on the ignition then your dials have been turned off.
They do not change anything if you have a custom map loaded. If you want to turn back on the dials and remove the custom map then you need to log in to the ignition and under "Edit module parameters" and select "Flash Advanced Curves." After you upload to the ignition your dials on the front will become active.
--
David - Tech Support
Daytona Twin Tec

So according to Daytona even the Initial Timing Dial does nothing with a Custom map loaded in to EEPROM.


Since I have heard both now..that neither dial works..or from elsewhere that the Initial Timing works,....I have e-mailed him again to get direct clarification from Daytona if the Initial Timing does or does not work with a Custom map.


If it does not, then the differences the guys saw on the Dyno rig as they turned up the dials where merely the effects of the bike warming up, the bike bedding in, the dyno warming up, ..and dyno testing technique.


I'll update when I hear back form Daytona.


But yes, as you say ..9 & 9 seems very aggressive...which is how come I started looking at all of this. The day I got back home and lifted the seat and saw that setting of 9 & 9...if the setting had been around the correct 2 0 or 2 2 dial positions i'd not have looked again...just that they were at 9 & 9 and my download of the module showed it to be in EEPROM mode when they said they set it to FLASH mode.



and I knew the EEPROM table i had previously loaded was a Rico IV....and comparing my download to the Rico IV..it is identical.

I fully believe the Initial switch is active regardless
I had a dyno session years ago were I left the switch retarded 2 clicks and the bike was noticeably more tractable on the ride home !
That spawned the Jester series of maps

You can't set it to flash and use the dials on the fly once a map is loaded. You have to hook your computer up to to revert back.

Yes, i get that you need to plug the computer in to do the swap between FLASH and EEPROM.

The guy that did the head work and consequently the build , knew that you had to swap it with PC-Link software...but what he did not know was that youhav to Click the UPLOAD button after you change the setting in Edit Module Parameters box.

He just changed the setting in the software and clicked OK.
He never knew you had to do an UPLOAD to make the setting change 'stick' in the module.
If you have no custom maps to hand..first you do a download and download the Factory set 0 0 map from EEPROM.

He tried on a TC88 to do an UPLOAD and said it gave an error...I told hime "yes, it will do that unless there is a map loaded..


All a little bit worrying he did not know that ..wonder how many other bikes he may have done, changed settings in the software but not uploaded them to the module.
