OBII for V8's
Diagnostics for the Lotus V8 engine

After the success of FreeScan for the 4 cylinder fuel-injected Esprits. Lotus Esprit World has been looking into diagnostic software for V8 owners. The Esprit V8 has a different type of ECU than the 4cyl. Esprits, so needs different software and hardware. Luckily Lotus used a commonly used system and software and hardware is available at very reasonable prices.

Diagnostic products like FreeScan and the OBDII systems shown below are worth their weight in gold to an Esprit owner. There's three types for the V8; the first is like FreeScan, you'll get a cable and software and will need to connect it to a compatible laptop. This software gives you the most information and also gives more features. The second is more convenient (if you don't have a laptop), but offers less information. It's basically a hand-held device that will give you a code reading. You'll then need to look up the code for the problem in the manual. If you want a little more (and want to spend a little more) you can get a higher spec hand-held, which allows live streaming and the ability to store information and use it on your PC.

Many problems can be diagnosed before a visit to a garage and with the help of the Esprit communities can be fixed either by the owner or valuable information can be taken to the garage, saving time and money. Diagnostics normally pay for themselves pretty quickly, come a problem, you'll kick yourself if you haven't bought one. Both small and large problems can be found and make owning an Esprit less daunting.

Lotus Esprit World runs a 4 cylinder Esprit and uses FreeScan, but has purchased an EZ-Scan 4000 for evaluation. Gendan also offers the PocketScan code reader. Both readers are very useful and very easy to use. LEW can recommend both products for V8 owners. See LEW's guide to using the 3100 and 4000.

The products below will work on most 'other' cars from 2001. Whilst OBDII was implemented on most US cars back in 1996, the same law (EOBD) didn't come in here until 2001 (for petrol models). Most European manufacturers therefore only implemented the systems on petrols in 2001.

Some manufacturers, e.g. Ford, Jaguar, Lotus (on the V8), Volvo, did implement the systems on UK-spec cars from approx 1997, but most (e.g. Vauxhall, Peugeot, Citroen etc.) held off until 2001.

Please check that your Esprit is compatible with the following products, as early V8's use a different system.

OBDII PC interface with 96 V8's
I though you might like to know that the scan tool pc interface from Genden direct works with my 1996 V8. I know they run different diagnostics and there was uncertainty as to wether these tools would work with the earlier V8's

Ps keep up the good work

Users comments
Had my first chance to play with this stuff over the weekend. Install s/ware easy peasy. Plug the cable into the car. Not reading the ecu (although green light is on, so interface does recognise the ecu).

Re-boot pc - all connects and works fine. Did a couple of test runs with the logging switched on. Looks like a very useful tool. No fault codes stored so can't verify this bit. Did some "real time graphing" of speed/rpm whilst on the move - very groovy :)

There are some neat features on there too regarding 1/4 mile times which i'll play with at some point :D Will bring with me to stanton - any other v8 owners welcome to borrow/plug in.

Product details
The PocketScan Code Reader is a user-friendly tool for those new to diagnostics and light-to-moderate DIY customers.

It gives the user the ability to quickly determine the cause of the "Check Engine" light coming on. Once repairs are made, the PocketScan allows the user to clear the trouble codes and turn off the light.

It enables the user to read fault trouble codes (DTCs) from the on-board computers of Lotus V8 engines (from 1997), as well as all other 2001 and newer petrol cars and 2004+ diesels. The Pocketscan is also able to read cars using the newer CAN protocol (i.e. some 2003+ models, including the new Ford range and several new Mazda and Vauxhall vehicles).

This code reader will read/clear codes from EOBD diagnostics systems (this covers engine, powertrain and emissions faults). It will not read/clear codes from other systems, e.g. SRS, ABS or Suspension systems.

• Reads and erases Diagnostic Trouble Codes (DTCs) and turns off check engine light

OBDII Code Reader

LEW gets busy on Elise this time!

January 2007
A family member was having trouble with a 2001 Elise and wanted LEW to help. Unfortunately we had to spend our time on something else other than an Esprit. The Elise had the dreaded 'Engine Management' light on. The manual says go straight to your authorised dealer and not much else. Before making the trek to a dealer, we got hold of an OBDII reader from Gendan. This reader plugs into the engine management and can read the fault codes. 4 codes were given. 2 the reader identified and others were Lotus codes, so we needed to refer to the service manual. This device also allows you to reset the error codes, so you can see if they return.

This is a great device for anyone who likes to make an attempt at fixing their vechicle. These type of readers work on 1997-2004 Esprit V8's and any other vehicles from 96 on (see descriptions). More information can be found in the maintenance section of LEW and some of the readers can be found at the clubshop. ClubLEW members can also get a discount from Gendan on Code readers.

If you haven't got one, it's worth thinking about.


ECU Problems

For what its worth..
I have a 4 pot but it was diagnosed with a fried ECU - easily done apparantly. I was speaking to Christopher Neils chaps at Donny last year and they put me in touch with Bluestreak who can triage and repair ECUs.

They're in Hucknall, Notts, and on 01623 753300.

Triage fee was £25 and they send you a document with your diagnosis. I found them quick and fairly cheap. Moreover they weren't given any indication of my symptoms beforehand to give them an unbiased start point and they hit on the culprits quick and problem solved. Mention Club LEW and Christopher Neil to them as well - seemed to work well!

Some updated info from an Esprit owner from Gendan:

We don’t have anything Lotus-specific, which would cover systems like ABS, but the V8 engine ECUs were OBD-II compliant, so we can cover the engine.
In our experience PC packages work better with the Esprit than handheld tools, so we would recommend the EngineCheck package:
