Stepped away for a week and look at what is in the works! This is very exiting news!

I will definitely be interested in this service once it is all worked out. For those of us already in possession of the IM and FCE we should be able to recoup at least some of the cost by selling these items. With the new product we will finally get unrestricted power in all gears and hopefully even better performance with the control of the secondary throttle bodies etc.

It seems to me that offering alterations to the fuel curve in the ecu would be a desireable option for at least some of us. There certainly are a large number of FZers out there with Ivan's "full package" setup (Airbox mod, Ivans secondary plates, BMC filter, Yosh R77 full system {presumably no longer needing FCE, and IM}) and would be happy with Ivan's fuel tune right in the ECU. I would probably keep the PCIII (at least for a while) and could leave it zeroed out with the option of fine tuning at a local dyno if desired. Shouldn't be too difficult to make the fuel curve mod at least an option on the reflash with the understanding that some fine tuning might still need to be done.

Ivan, thanks for taking this on! It definitely seems like a wise business move to start dabbling in the ECU waters. I'm sure the GenIII will benefit from your hands if we ever see it!

I'm glad I have an 06, I'll hopefully be thrashing it at the track early summer with the new ecu, maybe those R1's wont pull away from me so much on the front straight at Road America.

Ivan is the man...

Ivan I would be willing to pay more if you would offer the option of fuel mods with this like the other companies I know it will be backed up with proven results from you.

My '08 is still friggin' stock for Christ's sake...

I'll drop her off and you can use her as as your stock baseline tester!

Would the IM still be worthwhile with the reflash or does it become redundant.

Ivan, your last post has me thinking about paying even more!! Just think...... having a little higher rev ceiling and a better bottom end with no restrictions has me also slobbering on my keyboard!!!
My 2009 usually picks up the front end just past 5500rpm with no clutch and just a whack at the throttle so to get it to lift 1000rpm lower would be fun!!!
I would also love to know does it feel any better at the 3000rpm to 4000rpm mark as we all know she is really weak there. I ride in the city a bit and coming around a tight corner right at 3000 and she just feels flat and almost like a bid fat 250. Just curious, I can’t expect everything gets fixed by this ECU re-do.
Can’t wait feel like a kid at x-mas, am I going to get a bb gun or socks again???

Will it eliminate the need for the Ign module to get the fuel millage back? sounds like it. Plus turn around time is a factor also. After I sell a bike I am planning on getting your combo set up anyhow.

I'll have some dyno charts some time next week....

I was not 100% correct about the sub-throttles only 90% open max...
(I was looking at only one of the tables)

There are a few sub throttle tables in there.... they open 100% in the upper gears, like my first dyno tests showed back in 2006.

There are more restrictions in there besides the sub throttles... the timing is held back as well in the lower gears... combine this with the subs and you get some of the picture. This is all old news anyway... Well documented from the beginning.

Again, I am very much against fuel adjustments without a pc3 or pc5 at this time.... too many different mods, and if it's not to your liking.... a big pain in the ass, and shipping expenses that you will incur and downtime too.

At some point I will try to graft one of my maps into it and see what happens.... I'm not up to that point yet. Still a lot of other stuff to test and prove out.

Most of you have a PC3/5 anyway.... this is what I believe is best for everyone.

When its all ironed out will you do fuel adj. if you can put the bike on your dyno for the tune?

I agree 100% with you Ivan. I still want to play with the fueling after the re-flash.

Ivan,
I absolutely understand your concern about doing fuel mods is most cases. There will be a lot of work involved; I've got many hours of driving my car around getting data logs and making adjustments (and I still don't feel like it's quite close enough to put on the dyno for fine tuning). Once you do a full tune for your fully modded bike, though, this new tune should apply equally (I personally think better) well as your E-map.

I would definitely recommend looking into making acceleration enrichment/pump shot adjustments for the first run of mail order tunes, though. It will help clean up throttle transitions (I'm sure you know this already, I'm just thinking out loud so to speak).

I don't care for the method of modifying the fuel by PC III/IV because it makes changes at a given TP and given RPM. An engine at half throttle and 5000rpm will need different fueling and timing going up hill as opposed to down hill. Load-based mapping is a much better method. As much as I don't like it, the PC is the only method we having for making changes at the moment.

Ivan
Any consideration of correcting the fueling vs temperature when the ECU is open loop/O2 sensor disconnected, or is that buried too deep in the fuel table algorithms?

I have a '10 that is bone stock. My last ride was a '97 Bandit 1200S with a slip-on and carb kit, that bike had tremendous bottom end, my FZ1 can't match it. If the ECU reflash will cure the FZ1's bottom & mid range woes, I'm in.

Regardless of tune, the FZ1 will never have bottom end like a bandit; it's a completely different animal.

Well, I was hoping a 2010 FZ1 with EFI & reflash versus '97 bike with carbs and a slip-on would produce better results. I'll wait for Ivan's responce, but you may be right. I want to hear it from the horse's mouth. If the bottom end and mids are significantly better, I'd be in.

^ It won't be a bandit down low, just like the bandit will never be a FZ/R1 up top.
