ECU Reflash, issue???

Allen D · 08-03-2016, 12:33 PM

I just got my ECU back from Ivan and I'm noticing something I didn't before..

When on the highway, in 6th gear, doing about 75mph if you have to drop the hammer and accelerate hard and quickly, I have all kinds of nasty chatter coming from the motor. It sounds like the motor is about to detonate. Before the re-flash it didn't do that...

It's only when in 6th and happens about 3000rpm. In lower gears I can run that thing to redline and nothing, put it in 6th and accelerate hard while on the highway and clatter and chatter galore. So much so I'm fully expecting my motor to give up it's magic smoke and shoot sky high...

Anyone else notice this?

I thought I'd ask here now since Ivan is gone until the 15th.

Thanks.

Are you using premium fuel?

Lumberjack · 08-03-2016, 01:55 PM

Are you using BAK? This needs more fuel at top end.
He will ask you to try another gas station - bad fuel maybe?
Check for air leaks in intake.
Keep us posted please - there is a few with issues.

try down shifting to 5th, it my understanding the 6th is overdrive and should avoid hard acceleration in 6th.

You are experiencing pinging. If I am not mistaken Ivan specifies premium fuel after the reflash.

BobBear · 08-03-2016, 08:22 PM

My 2015 Vaquero is stock and does this any time I try to accelerate from low speed in 5th or 6th gear. Scared me at first until I learned how to avoid it i.e. downshift.

Bingo... And not only after the reflash... Kaw specifies Premium fuel in the owners manual. I was able to run regular without ping after installing an EJK fuel processor, but it's back to premium now with the EJK off, and Ivan's flash in.

Yep, same thing here. After IVANizing, you gotta run premium. [I have gotten away using mid-grade a couple times, though, lol.]

I removed my comment....I have no skin in the game anyway since I leave my motorcycles stock.
I just find it amusing to read that people do mod this and mod that on their bikes, then get on forums and ask why their motorcycle don't run properly.
You'all enjoy!!

In the U.S. the ratings are as follow:

92 Premium
Therefore mid-grade is perfectly acceptable IMO

Mid grade may be acceptable to you, but you are giving the wrong information out. If the minimum octane rating Kawasaki says to use is 90 then you should use premium and not down grade to 89. Premium fuel in the U.S. has a octane rating of 91-93 just to be clear about your information. Best not to give the wrong information out and confuse people with opinion not fact.

I hate to ask this. But what is "Pinging" ? Is it the same as "Knocking" ?

Yes.

I had some pinging after the flash even running 93 octane, but only at Wide Open Throtle at around 4000 rpm. I still had my Power Commander connected, so I added 6% fuel at the top end, ping gone, bike pulls like a bat outta hell even in 6th gear and no downshift. Ivan offered to reflash but I did not want to mail the ECU out again. I am leaving everything alone now, bike runs great.

Lumberjack · 08-04-2016, 07:25 PM

I must ask if in any gear? Do you have BAK?
