GL1500 Max Cruise Control

Postby rocknon » Tue Jun 29, 2010 9:33 pm



Does anyone know how to get around or increase the max cruise control speed for a 1990 GL1500. I tryed switching the wires around so that the cruises unit thinks its in 4th instead of 5th but that did not work. From research it looks like Honda changed something in 1993 that causes this not to work. My cruise will go 75 max. Any help would be appreciated.

Yo Rocko, I've got a '93 mine tops out at 75 too. Not sure if I really want to cruise faster than that, lot's of deer on 80 through Nevada - the only time I thought maybe I'd want to go faster but...
Therefore I haven't researched it yet. I'll keep an eye on your post though. Have you combed through these forums? Seems like I saw something about this toipic.

I am still trying to figure this out. I am wondering if there is a way to trick the cruise control so that it thinks it is going slower than it actually is. Maybe put a resistor on the wire going into the cruise? Any ideas? Thanks

I did this on mine, and it works just fine. Got it from the German Goldwing Forum.

Remove seat

Stand on the right side of the bike and look at the mudguard.

Find the 22 pole plug and socket connector (C33) (coloured black - mine was in a black protective snap shut holder)

Remove enough insulating tape from the cable at the forward end of the connector so you can work on the wires

Find the red/white and green/orange cables. These are the ones you need to cross-connect. You can solder the wires if you wish. I just used screw connectors.

Re-tape the wires

Put everything back together

Have a beer. :D

Apparently this will work with all 1500 Aspys. Build yesr doesn't matter.
Have fun
David

Good tip...can't wait to try it out :)

However, for the sake of precision, what do you mean by 'cross-connect'...do you mean 'switch their positions' or 'connect them together' ?

Thanks for clarifying ;)

Sorry - I'm a Brit, and sometimes an expression that is clear in English is not clear to Americans or other nationalities.

What I mean is, cut the two wires in the middle (giving yourself enough room to work), strip the insulation back about one eighth of an inch, then connect the red/white wires to the green/orange wires, so they cross each other.
Hope this explains it better.
Cheers
David

Thanks David, that's clear now ;)

However, before I try this, can you tell me what it does to the cruise control exactly?

In other words, does it "fool it" on the max speed set of 78mph, or does it just null its maximum setting completely?

The cruise control box limits the engine rpm in overdrive (5th gear) to ca. 3000 rpm (about 75 mph). To keep the same speed in 4th gear, the engine rpm is limited to ca. 4500 rpm. The red/white and orange/green wires are the 4th and 5th gear signal wires. By cross-connecting those wires (that phrase again), the control box is fooled into thinking we're in 4th gear when we're actually in 5th (overdrive). I didn't find this out - I'm not clever enough. However, I can speak and read technical German, and I found it in a German Goldwing Forum :D

Ok I see...so if I understand correctly, in essence fooling the system by cross connecting these wires will make the cruise control work up to 4500rpm in 5th (now that's fast enough for sure lolll), but will by the same token wind up disabling the cruise control in 4th @ 3000rpm (as opposed to thinking it's in 5th @ 3000rpm)...if that's the case, that's no good at all, as I often ride for long periods of time on US secondary roads at that rpm in 4th gear. Besides, I find the elctronic cruise control on the 88 model to be somewhat inefficient...at various speeds it just jerks too much to maintain the speed, and it always falls off up to 10 km/h when it is set, unless you just hold for a few seconds)...I think the mechanical throttle lock is better suited (instanteneous lock) to control speed when I just need my right hand to satisfy an itch, pick my nose or squeeeeze my girlfriend's knee ;)

Sounds like you have clogged or porous vacuum pipes - they do get old as well. There's a troubleshooting section in the Workshop manual (you can download it from this site)

You're correct in assuming that 4th gear will be limited to 3000rpm. In my part of the world the secondary roads are 98% hardtop (blacktop?), so we don't need cruise control in 4th. I've done some more digging in the German Forum and I've found a way to get cruise control in 2nd, 3rd, 4th and OD. I must state here and now that I have NOT tried this out, so I cannot accept any responsibility for anything that goes wrong. However, it was posted over 3 years ago and there have been no adverse comments since then, so I think we can take it that it works OK. The only problem is that it's in PDF format, and I'm not allowed to attach it in this Website. I'll try and send you an E-mail with the file attached.
Cheers

P.S. Nope, can't add attachment in PM. If you send me a PM with your E-mail address, I'll send it that way

If my trusted mechanic 'blesses' the procedure, then that's all I need as far as 'garantee' ;)

Thanks David for sending the .pdf to martin.arial@live.ca ;)
