smckeown 1 Posted December 31, 2005 Is it the case that all ECUs dont work withthe pug rev counter ? I have read that both Emerald and KMS don't work. I have read that you can buy something from emerald to make the rev counter work, will that work with KMS also ? Tthe other option I saw on here recently was people talking about replacing the actual rev counter with an aftermarket one. Has anyone done this neatly ? cheers sean Share this post Link to post Share on other sites
petert 600 Posted December 31, 2005 I posted a circuit that I got from Haltech some time ago. You can modify the circuit by adding/subtracting diodes to match the number of ignition coils. It works well with the std. tacho. Share this post Link to post Share on other sites
huxley309 0 Posted December 31, 2005 i believe with the dta all you do is take your normal tacho feed and wire it directly to the tacho pin on the ecu Share this post Link to post Share on other sites
TVH 0 Posted December 31, 2005 Pug rev counter needs inductive flyback to determine revs. It won't work with plain 'digital' signal. What I had to do with MegaSquirt tacho output, was drive a small coil with it!! I was instructed to use a automotive relay coil, and that did the job.

DrSeuss 0 Posted December 31, 2005 you can install the rev counter drive from base model 306 clocks. Its a separate unit which works with an ecu feed. Share this post Link to post Share on other sites
smckeown 1 Posted December 31, 2005 can you expand on that DrSuess Share this post Link to post Share on other sites
DrSeuss 0 Posted December 31, 2005 Jaeger supply clocks where each drive unit is separate. ie the motors to turn the speedo spindle is on a separate circuit board to the motor to drive the rev counter spindle. It involves replacing the rev counter drive within the clocks with the unit from the jaeger clocks. This is all second hand information i might add. But hilgie informs me its perfectly possible. And from looking through the parts cd i concur. One point worthy of note, when we tried to do this with my mates xm clock drive, the spring is rather gentle and was broken quite early on in the swap.

smckeown 1 Posted December 31, 2005 cheers for that, so has anyone got this working ? Share this post Link to post Share on other sites
Sam 4 Posted December 31, 2005 Is it definate then Sam? I've tried coilpack BX ones which a few people said would work and had no luck (this was an omex ecu). I'm not sure theres a definitive solution for all aftermarket ecu's unfortunately. Share this post Link to post Share on other sites
DrSeuss 0 Posted December 31, 2005 aren't your clocks from a bx16v Sam? Share this post Link to post Share on other sites
Sam 4 Posted December 31, 2005 (edited) Nope 8v coilpack BX with the same coilpack as me and the same coilpack as a coilpack 306, coilpack coilpack coilpack, who'd 'av em. edit: added the fact it won't be the same coilpack as a GTI6 or S16 obviously, save you the effort of putting it to correct me Edited December 31, 2005 by Sam Share this post Link to post Share on other sites
IvarS 0 Posted January 10, 2006 I've sucessfully got my tacho working with MS but it wasnt't easy to figure out! Once I got it working, I soldered a circuit to a friend of mine who has the same problem (S16-engine in 205). It took 15 min and cost £1 In my case, one automotive relay didn't do the trick as for TVH. I had to use a 380V relay coil. Share this post Link to post Share on other sites
DrSeuss 0 Posted January 10, 2006 thats a nice ingenious little circuit there. If anyone wanted me to make them one i'd be happy to. I've just bought the clocks off ebay to take the rev counter drive from. It'll be a plug and play solution. Share this post Link to post Share on other sites
smckeown 1 Posted January 10, 2006 DrSuess if this is what I need to get my KMS ECU working with the OE rev counter then yes please, i'd make it worth your while sport! PM me of interested cheers sean Share this post Link to post Share on other sites
Mattsav 1 Posted January 10, 2006 Dont worry Sean. We're just waiting for the PCB's for our tacho drivers to be made (they are on the way just taking time). My electronics man has a CNC mill in his garage (along with a CNC lathe I sold him) so he's making a custom PCB for them. Similar to Ivars's, its uses a transistor to drive a specially wound coil. As soon as their finished I'll send one your way. Hopefully in a couple of weeks. We will be supply these FOC for 205gtidrivers KMS Customers Share this post Link to post Share on other sites
Sam 4 Posted January 10, 2006 It'll be a plug and play solution. Read as "bloody hassle to fit" and play. Share this post Link to post Share on other sites
DrSeuss 0 Posted January 10, 2006 (edited) Read as "bloody hassle to fit" and play.

pugrallye 0 Posted January 10, 2006 swapping rev counters does work, I use a saxo VTS one in my gti housing, workds beautifully with coilpacks, takes a wee bit of dremelling to fit though Share this post Link to post Share on other sites

pug_ham 245 3 Cars Posted January 12, 2006 I've also got BX coilpack clocks working on my car with direct rpm feed from the ecu. I had to swap the input wire into the plug on the back but works perfectly afterwards. Graham. Share this post Link to post Share on other sites
