Gunson fault finder for S2 2.9 Ford
Discussion
Are! chaps!
Went into Halfords the other day and saw a Gunson fault finder which says its for a 2.9 engine ford. Asked the choir boy halfords assistant if this was the one I wanted, suprise, suprise, had know idea.
Anyone know the number on the box so I get the right one. Thanks chaps!

Don`t know if this helps, info I had was as follows.
For TVR S3 there are two versions (actually intended for Ford
Granada/Scorpio EEC-1V).
1. The non Cat version with a 5 Pin ECU connector
2. The Cat version intended for 2.9 V6 Cat and V6 24 valve cat with a 3
pin ECU connector, Gunson part number: 4152
Never did get around to checking if the S3c was fitted with the 3 pin connector. I am sure someone will let you know where to find it to check if either 3 or 5 pin.

Just passing on a comment made by an 's' specialist, and not claiming to have much knowledge myself on this one, but...........
Watch out Gadgit, as TVR junked the airflow meters on the S3C and remapped the ecu, thus the gunson fault code reader gets a little confused. So said the specialist.....he may have been after my business!!!!
Any thoughts/experiences from those who use the gunson kit???(I have bought other gunson stuff and am generally impressed with it...)
Cheers, chin up.

Justto add confusion....a mate {in the TVR club} contacted Ford for info when he de-catted his S4C? (1990) and apprently the 2.9 is an export spec unit in his car.Hedid find someone very helpful at Ford.
If you nedd more info contact me on cerbera@vizzavi.net
and I'll try and put you two in touch to discuss the engine

Recently bought the 5 pin version of the Gunsen and it appears to work with my S3, I cannot remember the number on the box but I can find it when I get home. Reading the instructions (not something I usually do !!) it did say that it was for use with the export spec 2.9, unfortunately it only gave me the error numbers not exactly what I had to do to sort them out 
thats the hard one, I would have thought the £50-£100 or so is worth looking into IF you have problems. If your car is running OK why do it?
You may find a code and worry for no reason...the code may be an information code only.
If you are a keen DIY'er then it might help sort a car, but as you cant do much more than 'power reset' a standard ECU why not start there?
just an opinion of course

Gunson tester described is not that expensive - around £18.00. I have bought one and tested my own S3, it reported that everything was fine.
Matt - The best way to determine if it is going to be useful to you is to email me directly with a fax number and I will send you a photocopy of the important bits from the instruction book that came with it.

Come on lads, your not trying are you. mine's the early 2.9 and no cat!......... whats the number on the box that I need then ?
£18 is what it is at halfords, or there abouts, they have two in there and i just need conformation of the right number,..... a pint for the man who comes up with the right number!
All the best

I bought a Gunson'd Ford 3-pin Fault Finder(part no. 4152) to enable my own diagnosis of the car, a LHD 1991 model S3c. It is compatible with the outlet from the ECU all right, and should apparantly also be the correct one for the ECU of this Ford engine.
Background: the engine on my s3c often 'dies' when letting go of the accellerator.Usually this happens during the first minutes before the engine reaches normal temperature - but of course also sometimes when the engine is thoroughly warm ! After restart it idles OK , but the problem can repeat itself a couple of times after that. Alas - a Fault finder will show the culprit !
No - this Fault finder only reports a failure with power steering switch ! Since no s3s to my knowledge was fitted with power steering, I consider this error message to be ...somewhat lacking in credibility.
I'm now back to the procedure of having replaced in turn the throttle idler control valve, potentiometer etc but have not yet been able to find the culprit.
Any other ideas out there - either concerning the Gunson Fault Finder, or indeed a similar engine problem ?

4160 five pin is the one I have got for my non-cat S3.
I have similar running problems with my S3 but this now appears to be a problem with the ECU itself, it is only sending 3.3 volts to the temp sensor when it should be sending 5 volts, therefore when cold it only gets about 2.6 volts back (instead of 4+ volts) and thinks the temp is about 60+ degrees, therefore not opening the air bypass etc.. for cold start.

Peter Thanks very much for the info, recceived yesterday
... Cheers Matt.
Went to Halfords, got 4152.......Wrong one for my car.
Are you ready! If you have a 2.9 cat....... 4152
Non cat version 2.9 get 4160, for five pin.
Funny thing is you only get three pins in the box at the conector and they are coloured brown, green, and yellow. they only plug into three holes in the block.
No numbers come up, it flashes three times for 3 and so on. looks straight forward though, might place a report on it when used.

I don't mean to put a downer on this but I spoke to my mechanic mate next door about this and I got the general opinion that the Gunsons unit isnt that great - especially if it's picking up power stearing sensor faults from it's previous Granada roots.
The Ford ECU that was used in the Granada and our sacred S's isnt is programed fairly poorly to report faults unless you have what I think is called a Star code reader that the main dealers (and proberly the TVR dealer/specialists) use.
My mate's got all the proper code reader/diagnostic gear that most independant garages would have and to check my S and other Fords that use the same type of ECU takes ages to bring back the results, where as I've seen him use the same gear on my other cars, as customers cars with ease. He has many contacts in the trade which report the same.
Like I say, I'm not trying to be negitive about the Gunson device, but as my neighbours code reading equipment costs hundreds of pounds and I've seen the results, I remain sceptical about an £18 product that could do better.
