I'm thinking the cold start enrichment PBW needs to be increased. I admit that I pulled the air box out and installed the pod filter.
I had cold start issues. It would take 8 to 10 times hitting the start button before it would start. I tried the whole range of idle adjustment and it didn't help. I put the stock ecu setup back on and the bike would fire up on the second stab of the starter. I ended up sending it back to the guys at Vortex and they reflashed it to the latest settings. That was a couple of weeks ago. Now it will start on the second or third stab of the starter. The idle is a little slow at first but within a couple of seconds it's idling fine. I haven't tried changing the idle setting yet to see if I can improve it. I will say that I sure missed my Vortex while it was gone. It's amazing how much better the bike runs! I would recommend a Vortex to anybody with a 690.

Ah, that's good to know. I know it's the priming pulse for the cold start enrichment. I turn the key on, just stab the start button real quick. I do that 3 or 4 times and it fires right up. Basically like the old days when you gave the gas pedal three pumps before starting the car I'll call the Vortex folks and see whats up. thx for the heads up!

Makes sense. I've got the latest flash on mine and no trouble with start up.

My bike usually starts on the 2nd or 3rd try with the Vortex. I emailed them about it and they said they were working on it. I might send it back to get reflashed one of these days.

You read 84 watts ??? I assume you read 7 amps (7 amps x 12 volts) ...

This Vortex ECU is VERY interesting. I encourage you posting on this as much as possible ...

I checked the external pumps we are running in the rally car and they each draw about 7 amps and are rated for something like 40 gal/hour...bit overkill for the bike. the pumps are Walboro's. most of the external pumps are for higher flow auto applications and a bit overkill for the bike. that suzuki pump is looking like the best option.

Have you been following this thread? http://advrider.com/forums/showthread.php?t=708813 Maybe save yourself some r&d on the pump install.

anybody got a wiring diagram? im getting 12 vdc at the coil when you turn the key on but it goes away once the fuel pump cycles.
relay maybe? interlock? it would sure help to have a wiring diagram

good news is my berg is back together and makes me smile. i think the 690 is going bye bye when i get it fixed and ill build something to do the long dirt tours with no electronics and oil cooled, strong subframe to carry luggage with top of the line suspension

I hate giving up Would be nice to actually turn the 690 into a bomb proof platform, just to shove it up KTM's ass
