2010 ecu options

[johnnie27]

Greeting Johhnie upside down here in OZ

look i am no electronic genius, heck i can hardly spell! so looking for some help

Pro-tune offer a ecu treatment for the EVO and SP seimens thing
Rexxer Offer a ECU treatment also

i am wanting to fabricate my own 2-2 system like the sc-project job (since they will NOT sell there system w/out the mufflers (i want to use the shorty termi's) R6 style...and i am reluctant to fork another $1300 bucks ontop for a a DP ecu..i would just buy the termi kit and be done i guess?

does anyone have experience or knowledge on which is better ...benifits ...i am not looking for some amazing device i just want to be able to to a full system add a filter kit, and not lean off at the top end...please share your knowledge with me, in a simple form please...

johnnie thanks again

I have the same system as the RexXer with another name. I have mapped a 2010 EVO with the 2-into-1 Termignoni system and would like to recommend that, unless you have full tuning capabilities you shouldn't fabricate your own exhaust system.
It's primarily the exaust system that changes the fuel and timing table requirements. If there is little chance that you could get a calibration to work with the DP system, how are you going to get a good cal for a system that is different than that?
I know I sound like a wet blanket, but the truth can be ugly. In the carb days, there was a chance that you could get an appropriate jet in it, but not so these days.

I'm feeling the OP's pain as well. Just about every other bike on the market allows you to plug in xyz FI fuel management system to get the bike running right after some mods... The Duc shouldn't have to be so difficult or $$... Hopefully Ducshop or others will come out with an affordable option soon .

I think desmo is working on a stock Ecu flash and from what people are saying the PC-V is just about done. So for full exhaust and a filter that stuff should take care of the lean issue although it's funny that DUC could careless if our $13,000 to $15,000 bikes run right Wish they would have told me when i purchased the bike that it wouldnt idle till about 600 miles and fitting aftermarket exhaust would be super expensive and a giant pain in the ass. Sorry mini rant

I feel your pain... I think what I was least expecting was that it would take so long for aftermarket vendors and others to figure out the Siemens ECU. There's always a trade-off between getting new model bikes and the parts available for them, but this does seem a bit slower than what I've seen with other bike brands I've owned. The HM market might just be smaller so aftermarket companies are more cautious about sinking money and resources into figuring it out. Either that or this really is the gnarliest ECU to see the light of day

thanks for the reply..if i was to go the termi system i would just use the DP ecu that comes with it and be done with it i suppose (but i dont like the look of the 2-1 that much )...would you think the sc-project 2-2 full system would be ok, instead of making my own?...from what little i know that the old hyper and the new one are altimatley similar both closed loop under part throttle, (or certain rpm) as nothing is a closed loop at WOT? correct ..so is the issue with when you modify air intake that you need to stick more fuel in at WOT? i have read some on this at BikeBoy.org as brad suggested there is nothing wrong with making my own system...at the end of the day . the headers from arrow, zard , termi , sc-project ultimatley all seem to be the same...am i correct in assuming this? i have had custom exhausts made for my cars, WRX STI, EVO , GTIR pulsar, AUDI RS6 ,BMW X5 supercharged 4.6is and have always had wonderful results? are bike exhausts that different....please excuse my ignorance i am trying to get a handle on the best route that all...many thanks for your knowledge johnnie

Actually, bikes are different in that they don't have a mass flow sensor, Wide-band O2 sensors, or software adjustable boost.

Your comment about the DP ECU (i would just use the DP ecu that comes with it and be done with it sounds nice, but even if you did like the Termignoni 2-into-1 system, the DP ECU doesn't do a good job with that.

Whether you make your own system or put on a DP system, the bike should be tuned to get your moneys worth.

<so is the issue with when you modify air intake that you need to stick more fuel in at WOT?>

On fuel injected bikes changing the inlet configuration may have a small percentage flow increase but that will result in a small percentage AFR change, unlike with carbed engines, where a small change in inlet pressure will net a large change in fuel delivered, even if it doesn't significantly change the total flow volume (power) thru the engine.

The reason I always say they need to be tuned is not because I'm trying to sell what I do, but because I have lots and lots of data that says 'they all need to be tuned'.

ah, beautifully explained Doug, thanks so much MAF was the secret word to help me get it..i am talking with dynobike in oz today about the PC 5 i'll see what they have to say. thanks so much mate
