Speedometer correction

[DaveK]

The Z I am buying has had a 4.10 fitted. At the moment though there's no speedo correction. What's the best thing to do to correct it. I know that Mark sells correction gears - are they fairly straightforward to install?

I also noticed that Ecklers lists an electronic corrector that is programmable for different gears.

Any advice?

Thanks

Dave

Buy the gear from Mark. You unplug the VSS, and undo the bolt that holds it in, and slide the old gear out and insert the new one.

I would check with Bill Boudreau (www.zfdoc.com) he is now using an electronic box for speedo correction...will work with any ratio you choose. The cost is slightly less than the speedo correction gears and you won't have to go into the trans. I believe his price is $110.

Thanks for the info on Bill. It looks like it might be a bit hard to arrange though, he doesn't accept credit cards and I don't think a cheque from my canadian bank would be of any use to him. :confused:

you would have to do a U.S. money order/bank draft. he would have to build in his shipping cost's from the start, that's the tricky part, because most people don't know what the cost is in shipping to us here. can't send C.O.D. over the border.

Does anyone know if this is the same thing?

If so it may be easier to order through Ecklers, even thought they're more expensive.

Looks to be the exact same thing...as you said....only more $$$:-x

Have Ecklers 'borrowed' the idea from Bob? Or is it just a case of two people retailing the same thing at different prices?

Anyone know?

I don't mind paying the extra particularly if it makes it much easier to get (and there are a few other things I want from Ecklers anyway). But at the same time I'd rather support the original creator.

You could also talk to Eckler's tech folks and ask them if it will work on a ZR-1. The answer is likely YES.

ooops apologies to Bill if he's reading... :o

I'll email him and see what he says.

I'm running the gears from Mark, but they are for 4:30's. Never-the-less, I'm not sure Mark can get the gears anymore, you have to e-mail him. If he has some in stock jump on them, they're always back ordered and probably next to impossible to get anymore(gears that is). The gears are much cheaper but if not available you need to deal with Bill, he'll make it right.:mrgreen: It is a bummer he don't take plastic anymore, I didn't buy a B&B ZF from him because of it.:cool:

Just looking at the instructions on Mark's site about the gears, you need to remove the drive shaft and access the gearbox. What's the best way to achieve this? Ramps? Axle stands? Also I assume the car has to be fairly level - I can't just lift one end?

Thanks

Well, I have a ramp system I used/made, you can see it in the website in my link. Level is best, and safest. You could put it up on jack stands all the way around, just take your time, the more room under there the better things seem to work.:mrgreen:

[DaveK]

Hey that's a neat looking system you have there. Thanks for the pointer.

This unit seems to be very popular. Do a google search for some articles about it. You can purchase it direct from the manufacturer.
