As some of you will know, we have had a few problems with the drivers tacho circuit not driving some counters correctly, yet others are perfectly fine.

I would like to build up a picture of what works properly and what does not, so if you could possibly reply here and let me know how the tach performs on your car and what car/tach you have.

So, all i need to see in thsi topic is as follows:


Driver bought: DATE:

Car is: Saff2wd / Saff 4wd/ Escos

Tach is: Std/stack/elliot/ etc etc

Performance: Works fine/slow/1/2 speed...

Engine improvements on ignition side:
Any problems? Missfires? Its better, smoother? Worse?

You will be pleased to know we seem to have found the solution, but want to run all possible scenarions through it before we start to retro fit the solution to all our customers products.

Many Many thanks for your help in this research, and thanks for bearing with us. As promised, we havent forgotten you.

 

 

My 3 door you have at the moment worked half speed with standard tach, Every thing else worked perfect

My saff 4x4 k6 ssy you did about 12 months ago would sometimes work after a while than sometime not really work at all that was with standard tach. Once again all else was spot on seemed much smoother to drive and never had a problem with it

Driver bought: DATE: 8.2.07

Car is: Saff2wd / Saff 4wd/ Escos (3dr)

Tach is: Std/stack/elliot/ etc etc (std)

Performance: Works fine/slow/1/2 speed... (dont work at all)

Engine improvements on ignition side:

Any problems? Missfires? Its better, smoother? Worse . (no problems )
.on second driver ,still not working.used this instead

 

Can you confirm that works fine then mate, as i have tested that personally and it wouldnt work.

 

stu i think it only works on 2wd and 3dr, it deffo doesnt work on an escort.

as i've also tried it on an escort and had no joy.

havent personally tried it on a 2wd or 3rd.

 

Was my own 4x4 saff i tried it on as its seemed the simplest and most obvious solution.

 

Coil dwell overlapping will fool that circuit

 

im quite sure jason is now using a saff rev counter ,with that wiring and it works

 

Driver bought: DATE: End Feb 07

Car is: Saff2wd / Saff 4wd/ Escos 2wd Saph (1989)

Tach is: Std/stack/elliot/ etc etc Std - no mod was required

Performance: Works fine/slow/1/2 speed... works fine

Engine improvements on ignition side:
Any problems? Missfires? Its better, smoother? Worse? Have a misfire a 2K when engines cold

 

Ok, thanks to Simon Johnson for his technical support and Mick Clayton for the loan of his car all day and night, we now have what we hope to be a 100% solution for those people whos rev counters are slow / spurious or just plain dont work in:

Escort Cosworths

Sapphires from 89>

Anycar running an aftermarket tacho.

Unfortunately we cant test a 3door or early 2wd sapphire with this yet so will send out the retrofit solution for now and await their feedback.

Its a very easy DIY mod too. So anyone with problems, contact me on sales@remapping.co.uk and i can fire out the instructions and components tomorrow for Friday delivery.

 

Driver bought: DATE: April '07

Car is: Escos
Tach is: Standard

Performance: Works fine/slow/1/2 speed... works ok until 2k rpm,which then halve itself
Engine improvements on ignition side:
Any problems? Missfires? Its better, smoother? very slight unstable idle, but that could be due to a leak of vacuum, but haven't really drive it past 2k rpm, dunno what the true rpm is so don't wanna risk it. It does pull cleanly upto 2k tho

 

Arnie, i will mail you teh instructions right now as you can probably sort a component locally far faster than i can get it to Hong Kong.

 

i take it this is not the coilpack conversions? as im after doing this soon.

 

Yes, wasted spark is often known as a coilpack conversion.

 

does that mean you can run smaller gaps with less missfire.... Gunna start a thread. Sorry.

 

boXXer,


Yes, BUT, You can run bigger gaps without missfires too which also
improves idle quality and emissions.

 

Doh, thats what i meant. So in theory, it SHOULD burn better?

 

Bingo

 

driver one of the first ones

2wd saff

std taco

no probs

got rid of all miss fire probs

 

Big up to STU for giving a shit as a lot don't when they have your money, they run, RESPECT CHAP.

Just installed the wasted spark board in the ECU tonight, not sure whether it will work OK with a MK2 Escort RS2000 revcounter though....!

Not tried it yet - any other Cossie MK2 Escort owners with coilpack conversion here?

 

Stu

P8 with wasted spark enabled in the software (not converted wasted spark conversion) doesnt run with a sapph 2wd clock, reads half, but you probably knew that anyway

 

Ive not seen a MK2 escort rev counter actually work properly when its still running a MK2 escort engine... so your chances are slim at best...

e-mail me on sales@remapping.co.uk and i can send you the upgrade instructions though. May improve your chances from slim to thin.

 

Done, you have email

 

There you go Stu [/i]

 

Rodge.

Expect a parcel in the morning chap - been a long week and today was the only time I could post it

 

H reg 4x4 saff
taco spot on
idle perfect
best thing i ever fitted on car

 

No problem Graceland, no real hurry, had the (unfinished) car for years

 

your address in the "paypal address panel" is the one I was supposed to send it to yes?

 

Yes, that's the one

 

Driver bought: Within the last 6 months (Blackpool weekender, minus a month or so)

Car is: Saff 4wd

Tach is: Std

Performance: Works fine following the supplied instructions (the little red wire in the pic, soldered to back of tach)

Engine improvements on ignition side:
Any problems? Missfires? Its better, smoother? Worse?

NO PROBLEMS NO MISSFIRES

Great conversion

 

Driver bought: DATE: 29/3-07

Car is: Saff2wd / Saff 4wd/ Escos Saff2wd

Tach is: Std/stack/elliot/ etc etc std

Performance: Works fine/slow/1/2 speed... seems to be slow and showing only half the rpm..

Engine improvements on ignition side:
Any problems? Missfires? Its better, smoother? Worse? sounds better, but not yet tested on the road.

 

Driver: Old version 1 unit

Car: Escos

Tach: Std

Performance: Fine after mods(see below)

Engine improvements: Random misfires have now all disappeared,can now run larger plug gaps with hard plugs........motor feels generally transformed.....

Mods: I have modified the version 1 coilpack driver and the revcounter as per Stu`s instructions and it now reads ok........did read half revs`s before...

 

Driver bought DATE: 18-10-2006

Car is: Escos.

Tach is: Standard.

Performance: Works fine.

Engine improvements on ignition side: Very mooth throughout rev range, good stable idle.

Any problems? Missfires? Its better, smoother? Worse? No problems.

 

Driver: Version 2 unit fitted during live map in Aug 2006

Car: Saff 2wd running L8

Tach: STACK

Performance: STACK set to 2 cylinder to get correct reading

Engine improvements: No miss fires, wet weather doesn't affect it now

Mods: None other than setting on STACK

 

No probs here using on my Tina but using sierra clocks

As always Stu top job

 

for the Sunday browsers...

 

I forgot to add on mine Stu, that I had both the revision 1 and 2 drivers on trial in my ECU and both had no tacho problems, except if the core voltage at the ecu dropped below 11 volts (alternator failure) then the tacho stopped working

 

I'm running 2 of the conversions

standard mk2 escort revcounter reads zero (probably wiring problem though)
standard cortina mk5 revcounter reads half

engine performance good, no misfires
