Has anyone purchased a diagnostic device for pre 2000 ?

I have a Freelander 1999 and two MGF's 1996 and 1998

Great if you can help

Yep, the T300+ is probably the cheapest tool available.

I have one and can vouch that it covers the early ECU's and it will code fobs to the 5AS alarm system too.
Any problems with regards getting stung with customs ?

I've noticed many don't say about programming Rover fobs, do they do this out of the box or do you need an additional module ?

I assume they can only do 5AS and not Pektron ?

Cheers.

Pre 2000 diagnostics

Please send details of where to buy the T300+ diagnostic reader (your Chinese contact). Also where I can obtain the 5AS connector. I have a 1999 MGF 1.8 i not VVC. Many thanks,



I had no problems with delivery.


It didn't come with the 5AS lead, but this is easy enough to make up.

I believe this tool will code the Pektron fobs, this is based on information I have got regarding the software updates for the original tool, version 9.20 onwards has this capability.

I haven't played with the tool much but can confirm that it does the following....

Reads and clears faults on the following ecu's

MEMS 1.6, 1.9, 2J, 3.

It also gives live data and allows you to do actuator tests, ie turn on the cooling fan etc.

Fob coding to the 5AS, reading and modifying the EKA code.

Security match the 5AS and engine ECU if either are replaced.

The 5AS options require a different lead to the ECU diagnostics but this is easy enough to make or it can be bought made up.

I have yet to investigate the Pektron fob programming as I don't have access to a vehicle with this system.

I also vouch for the Technozen's recommended device. I've bought one and it's able to do what's advertised on the box. It has been useful with other cars as well. The available features and capabilities are highly variable per a model basis, but on MEMS it covers all the things I need.

Although I didn't need this feature, I've also tried the 5AS connection and it was able to talk with the box.

One (very minor) issue is that reading live data will make the motor stall (on my Rover 414 with a 1.9 MEMS). It looks like the polling rate (the speed at which the diagnostic box is requesting data from the ECU) is way too high. The ECU will be too busy with the requests and will not be able to actually control the engine. In any case, I'm not using this functionality. It was just by curiosity more than anything else.

Cheers,
Dan

I can confirm that this programmer will code Pektron fobs. I did two last weekend.

The menu system is a bit vague because the 5AS programming is available under the 100/200/400 entries and the Pektron SCU programming is under the ZR/ZS etc.. even though these vehicles came with the 5AS prior to the facelift.

Anyway... it works.

I initially used the OBD cable that came with the unit and had live data with it from my MEMS2J 200VI and a MEMS1.9 Rover 400.

I then made up a lead for 5AS programming and decided to add a switch which allows me to use one lead for MEMS and 5AS, this lead gave me live data on MEMS1.9/2J/3.

Since the weekend I have had live data on a Jag XK8, Vauxhall Astra, Rover 25 and an MGF.

Thanks i'll try the OBD cable for live data,

what are you switching to be able to do that???

The 5AS uses two data lines, a separate IN and OUT. On the diagnostic connector these are pins 3 and 1.

MEMS uses a single bi-directional line on Pin 7.

Pin 3 and Pin 7 end up at the same pin on the DB25 connector at the T300 so the switch simply connects the correct one depending on what the lead is being used for.

Many thanks, I will try to mod my lead and see what the results are on my unit.
I will let you know the outcome

Once again many thanks
