Hey guys,

Battyone, the following link shows what another UK race ECM user did to solve the problem I'm having:

Does this look about right? Also, don't forget about me! I still would really like to take you up on the offer.

Harry

That only shows the changes in timing he made. There are some strange leaps adding 10 then pulling 4 degrees ??? I would blame the warm up table, there must be a big step change as temp rises.

LittleJoe ran an EBR race ecm, although heavily changed by TwinMotorcycles. When he fired up there would be a point where the exhaust and engine noise changed dramatically. My bikes running modified stock ecm did not show the same behaviour.

All I'd do is download your eeprom and compare it to stock to look for obvious differences.
However ignition timing is useful for getting a stable idle, it's where I'm working running on E85 as it would stall at idle.
So logging the stall point would give us an area to look at.

I know you are all clear on what needs to be done but don't forget there are specific tables for idle which are important in the transition...

I'll just use tunerpro to compare everything relevant. I'm pretty sure this is something very specific to the race eeproms.

Probably swap a spare ecm to "prove" it's not a genuine bike fault too.

Gotta get Harry here first though, or get him hooked up with EcmSpy and he can email his eeprom.

My EBR Race EEPROM (2010 XB) is very little more than a remap, the firmware is the same as a stock ECM. There are things which I would have done which they chose not to. Very conservative in my view and not something that would ever win a race.



Having ECMSpy is a good thing. I'll make you a cable....

Pash, is yours a complete race ECM or just the race eeprom? I've had one -buezd - ecm that supposedly had a race eeprom but was only a mild re map.

Completely pointless as it left O2 and closed loop running live.

You're only gonna get smooth running, better response and more power by running a fair bit richer than stoic... Which the TM stg 1 does by a long way. My race bikes run richer still.

Even when I ran the full TM eeprom -on stock ecm-my bikes sounded completely different to Joe's -race ecm- on warm up. Suggesting some difference in warm up tables, or as you mentioned idle tables.
I don't use my monospy laptop online anymore, but from memory there is/are temp offset tables just for idle. However from my small experience of adjusting idle settings - required by E85- ignition timing made the most interesting changes.

For anyone wondering why I'm messing with E85, at the moment most petrol burning classes in drag bike racing are allowed to use leaded race fuels. But we are likely to be forced to go unleaded very soon. There are no unleaded replacements currently available to replace the up to 120 octane leaded currently popular/required. E85 has potential, but it's behaviour is a little peculiar.

Not sure what the difference is cos mine is from EBR with RACE USE ONLY milled into it.

I bought it out of curiosity really. There is no substitute for a dyno.

But as you know, you are only interested in power at WOT, and at WOT the O2 sensors play no part in operation apart from to richen the mixture if it is weak. That is to say you can have an ECM that uses O2 inputs, has a closed loop area, but has tip top power...

Hey guys,

Thank you both for discussing my ecm woes. I'm going to try and get hold of ecmspy tomorrow. Pash, I would very much like to purchase a cable from you if that would be possible? Let me know how you would like me to pay. Battyone, if I can figure out how to use ecmspy and send you my current map then maybe you could help me over the phone (once i have my lead)? Only if you have time obviously. You will have to tell me your favorite drink so I can send you a gift!

Thank you again everyone, I'm very grateful.

Harry

So Your ecm is the EBR race -programmable? - not just a stock with new maps, surprising that it's only got slightly different maps. You'd think you'd get a bit more for your money

As for the last part, yes I'm always looking for wot power, but idle and driveability are incredibly important to me too.
There's nothing worse than a race bike that doesn't start well, idle nicely and respond smoothly to tiny amounts of throttle. The petrol burning 1125 race bikes pull smoothly from tick over.
Going to take some work to get the same on E85

But imo stoic is no good for anything other than emissions. Even more so on a twin.


Harry no worries, Pash's cables are top notch - I've got 2- and I'm sure you'll get all the assistance you need to get up and running on here. The biggest head ache for me was getting the cable connected and working.

Think we will have to agree to disagree then...

We normally do

The TMstg1 maps will have an 1125 idling at low 12s, accelerating at mid 12s or richer and wot at high 12-low13s. There are a few owners on here who are very pleased with the improvement. Makes a much nicer bike to ride.

Stoic might be great for gas turbines but it gives crap rideability on a 103mm bore.

If the 1125 was fuelled properly they might have sold a few more and not had to resort to a fire sale. Maybe they should have made sure there was a powercommander available straight away. But no they sell their own "race" ecm with tiny pointless changes, that seem to cause more issues than they fix.
Thanks dog for Gunter and Ecmspy

We'll have to wait and see if Harry can get sorted with monospy or get up to me and we can do some data logs

Not sure gas turbines run at stoichiometric.

Anyway, you know what works for you and I can't argue with that...

Thanks loads Pash for making me a lead - I have PM'd you. Looking forward to receiving it!

I have downloaded ECMspy but don't want to activate it until I have found out which ECM version I have. £38 per database so don't particularly want to make that mistake too many times!

Can't wait to have a go! I hope you can help Battyone because I have a rather uncanny ability to wreck things

Right, have received my lead from Pash.

Going to plug it into the bike tomorrow evening to find out which ecm version I am running then pay for ecmspy.

I will then need help!!!

Hey guys,

Battyone, I have PM'd you my EEPROM if you get chance to have a look. The lead and ECM spy are awesome by the way

Harry
