Ecumate limitations
Discussion
Later this wk a nice new ecumate will be coming to my door, I have a good idea of what it can analyse etc.
After I've used it to check various systems are working properly,
Am I right in thinking it won't pick up any info on speed sensor and or speedo itself.
I'm trying to ascertain weather I've blown my speedo ( box) when blowing 100 A fuse offering up alternator with batt STILL connected.
I have worked on cars before ( honest)
Any help would be very much appreciated.
I'm pretty sure I've goosed my speedo as its reading 5/10 mph soon as ignition is turned on and before my blunder it didnt do anything until 20 mph! (Calibration) apparently!
The 10A fuse on fuse board if that had blown the speedo would not work at all ?
When driving the speedo reads 40mph when cars actually doing 25mph so its gone bonkers, a bit like me!??!!!
Any guidance would be very much appreciated,
Thanks Al

What does the speedo box actually do ? I spoke to Caerbont , they said the box is not needed and did not understand why they fit this box ,the signal from the diff to the speedo works without the box .
After speaking to a Cerbera owner He told me the black box operates his door locks after a certain speed ,not sure if its the same on the chimaera.

Not to my knowledge.I have opened and closed my doors a couple of times over the years at speed on the motorway because I have stupidly not shut the door properly and only realised later
The box converts the analog transducer signal into a "digital" form that the ECU can see. The speedo itself is OK and sees the signal but without the adapter box, the ECU will think that the vehicle is stationary and this screws things up. See page 40 in the manual.... http://ecumate.com/docs/Ecumate%20inst.pdf
ECUmate will flag up if the ECU sees a speedo fault, shows the speedo signal and if the ECU is going into is idle mode/sequence.

Is this box needed for after market ECU`s . ? I might junk it !ECUmate will flag up if the ECU sees a speedo fault, shows the speedo signal and if the ECU is going into is idle mode/sequence.
Dragging around in my memory.....don't the early cars not have this, and it was only when TVR went to the T5 gearbox that they had to introduce the speedo conversion box?
Or was it the introduction of the 14CUX ECU that made the difference?
All i can remember is that it is a TVR-created mismatch of bits that requires a box to convert signals.

Analoge/digital.
I've just dis connected alt main feed re connected batt and speedo still reads 8mph?
So now I need to invest in a volt meter, its about time I learnt!
I realise that various bits require correct current etc so you use it to assertain faults, etc, that's after ive took it to someone who knows what there doing to sort a problem of my own making!
Expensive home mechanics!
I should buy a bike with a carb!

Maplins, multimeter is less than £20. Mine was £7.99, bright yellow. Can't see it in their online catalogue, however.

Its not the meter thats expensive its my blundering about in the engine bay.
Just have to wait until my ecumate arrives and see what that says.
Hey Alun too late now you've splashed out on one, but you could have had a play with my Ecumate, if you want I would be happy to come over at the weekend and help you to use it, or to compare what your seeing against mine etc (assuming they should give similar readings), I just have to fit my new starter motor first (providing it arrives in time I will fit before the weekend).Just have to wait until my ecumate arrives and see what that says.
The important thing to look for is the speedo input the ECU sees that ECUmate reads- this should be 0 MPH at less than 3 mph, and then jump to between 30 and 50 MPH once the car goes over 3 mph. The speedo transducer box is designed to do this on the T5 gearbox cars, so its not a fault if you get these odd readings.

Hi Paul, my ecumate should arrive on Wednesday so I'll use it ASAP.
I'm not in rugby at the wk end, work commitment so will stay at a friends house overnight.
I was going to mot it this wk but I haven't got much time so cancelled it. I really can't work out what I could have done to my speedo, I'm now deciding which fuse bourd I have fitted!
Really appreciate the offer and if I'm still trying to work it out by next wk I 'll give you a shout.
The car is due a service at Power so if all else fails I'll let them have a look.
It could just be stepper motor out of position and somehow I've goosed the speedo but I bloody hope not.
I have sometime in the morning so I'm checking earth points etc just to tick it off my Maybe list!
Regards Al

No Problem Alun - I'm no expert and read most posts with awe at the knowledge people on here have, I am looking for an excuse most weekends to get out in the Chim - with the Ecumate you can manually control the stepper - although I haven't worked out what help this is other than to prove the stepper motor travels in and out., not sure the unit is going to help with the speedo problem though.I'm not in rugby at the wk end, work commitment so will stay at a friends house overnight.
