wyland said:have you noticed the bike vibrations between 3-5k calm down a bit? there was discussion on hand numbing between that range.
brookst333 said:Wow, after reading the maps I'm tempted to just remove the flys.
When I installed my PC V in December, there was not a map included for a 2011 Connie with flys removed.
I don't want the bike to run lean during steady throttle ordinary cruising.
Might overheat the catalytic converter also?

Just think one injector gets a little something in to plug it up a little and that cylinder goes over temp. You've removed the safety richness and that's my 2 cents worth. The butterflies, I took mine out and could not see any improvement, but them back in and saw no difference. Don't see the big deal on this.

Rev Ryder said:Very interesting Fred. So what I'm looking at is only the amount of fuel the PCV is trying to add or subtract to meet some target AFR, correct?

I have been conversing with the Dynotronics Tuning folks, who broke the ECU code on the C14 and on which Guhl bases their flash.
Privateer said:Fred -
A lot of the ZX14 guys are running A/F meters on their bikes, especially the ones with the PC5 and Autotune who frequently tweak the map. They don't all agree on what A/F ratio to run, just that it should be higher than 9.
Privateer said:How do you define "slightly rich", Fred ?

The Guhl reflash has absolutely nothing to do with anything at all that Dynotronics is doing or did. Guhl downloaded the first ECU I sent them about a year and a half ago and cracked the code on it then.
Privateer said:Heh, not what Dynotronics says. This gets more interesting by the minute. What is the difference between what they do?
By the way, the ZX14 ECU was first downloaded in 2007 I think, by HealTech, trying to figure out how to get rid of the decel backfire without losing the gear indicator. They couldn't figure out how to do it, and gave up on it 2 years later. Guhl is the first I heard of to offer a reflashed ECU for the ZX14 engine.

I have no idea what Dynotronics is telling you, but they are two totally different companies and none of the work that Don Guhl is doing is based on anything that Dynotronics is doing. I've been working with Don on this project for almost two years now. He and I developed this tune totally on our own, and the primary focus of it is to open the secondary butterflies. The adjustments to the fuel map are small potatoes compared to the butterfly map, and the fuel adjustments are pretty minor, it just tries to reduce some of the over richness that Kawasaki programmed in to bring it in closer to 13.2 to 13.4 range (~ .89 lamba). The big benifets of the Guhl reflash are from opening up the butterflies further and sooner. Go back to page one of this thread and watch the Utube videos I posted showing the butterfly opening rates.
John, Yes we open the secondaries sooner, ramp them open quicker, and keep them open till redline. We also adjust the timing, remove the restrictions, > adjust cam mapping,raise the rev limit, and speed limiters. We were the company that broke the coding on the GRT 1400 , so I'm happy you liked the > results of Gulh's tuning, as it is based on our research. BTW 13:1 is a bit too rich for the GTR1400
Fred_Harmon_TX said:One more thing I'd like to mention. My wideband 02 sensor is installed upstream of the CAT's in the header, and my secondary air system is plugged. This means my 02 sensor is reading the unaltered output of the exhaust. Many tuners will simply insert an O2 sensor up the exhaust pipe AFTER the CAT's and this can skew their results, as will the secondary air supply system if it is not plugged.

Fred_Harmon_TX said:I capped off the secondary air system on my bike because I have O2 sensors installed in my exhaust, and I didn't want the injected air to mess up the readings from my sensors.
