You have a seized sub-throttle shaft and will need to either fix it or get new throttle bodies... Most likely the sub-throttle motor is burned out as well. Ivan

Sounds to me like it's very lean... the rpm range that you describe does not have fuel cut. Is the O2 sensor still connected? If so, try disconnecting it and see if it improves. If not, you are going to need to add fuel somehow. Try the O2 first and see. (one step at a time) Ivan

This is 100% not from fuel cut... this is either a kinked fuel line or caused by another modification that has been done. (Fuel cut is way above this range) What else has been done to the bike that is performance related? Subthrottles stock? Power commander? Do the subthrottles...

Thanks, Ivan

What rpm range are you having problems? Ivan

This will not work across the entire rpm range... this was done last year by another member on the other board. Basically, it just moved the fuel cut range up by appx 1000 rpm. The only way to do it from outside the ECU is to use my FCE.... I figured this out back in 2006 and it cannot be...

I must have sent you the wrong sheet... (very sorry) 1600-1700 is correct. Ivan

Anyone interested in an ECU flash made with commercially available software should read this: Flash Tune Results - FZ1OA Message Board I would never use this product or have my name associated with it as there are too many mistakes in it's function... I have had to reprogram a few ECU's that...

Jeff, There are some things here that do not make sense.... The chart is showing the stock rev-limiter for both runs... this indicates to me that it isn't my flash. Before you go saying that nobody touched it, I have only one flash file that I use.... everyone else's would have the same...

The biggest problem tuning this bike with a wideband is that the readings are very different than a gas tester at small throttle openings.. this is why when you remove the fuel (because the wideband says it's rich) the driveability goes to shit. I've used both to get the tune where it is...

This ecu has to be cut open to get at the programming that's in it... with that said, I cannot tweak the programming that you already have to add anything to it without cutting your ecu open. (I won't do this for anyone due to the potential liability) The programming that I have made for this...

Just save the map before you go... I have had many ask me to send it again after they went to have it tweaked. Ivan

Code 19 will appear when the key is on.... bike in gear and sidestand down. With the FCE... this is normal. If you lift the stand, the light should go out... If not, then something is wrong. You either have bad connections, or bad crimps or the FCE is bad.... most of the time it's the...

Cougar (Jim) took his bike to this shop for the "test". He should have known better than to go to a competing vendor... I'm surprised that they didn't show more of a gain. Ivan

Here's one on ebay: B188 27639 01 02 03 04 05 Yamaha FZ1 Main Relay Fuel Pump Turn Signal | eBay There are others on ebay. I'm pretty sure it's located in the tail section somewhere.. shouldn't be very hard to find. Ivan

Code 19 runs through the relay unit (combination unit), if you can't get rid of it by jumping the sidestand switch, you need a new relay unit (combination unit) most likely. Do you have an FCE? If yes, then you need to check the connections. With the FCE, code 19 is normal when the key...

Probably cannot... there is an error code... need to solve that first. :) Ivan

Give me a call on the phone during the day please... I don't type very well (old and slow with 2 fingers) I'm sure that you will have many questions... this is much better answered be me in person. :tup: Thanks, Ivan

I have one of them... bought it brand new when I was 25. Ivan's Performance Products One of my favorites..... ever !! Ivan

You can use a PC3 from an R1 2004-2006 with no problems.... the map needs to be for an FZ1. Ivan
