NEW PRODUCT
ELECTRONIC AUTOMATIC GEARBOX CONTROLLER
Paddle shift control for automatic gearboxes. Automotive have developed a package to control electronic automatic gearboxes independently of the complex integrated systems found in modern cars.
This enables a power train to be transferred from a donor car for a new purpose such as a space framed off road racing car or a kit sports car.
Alternatively, where an existing installation exists but found to be inadequate due to exceptional demands such as rallying, this system can be integrated with many original engine management systems.
Current applications developed and available are:
ZF4HP22/24 as found in Range Rover 38A, Discovery 2, and Defender models;
ZF5HP24 as found in Jaguar V8 models;
JATCO480E as found in Rover and Freelander models.
Standard package includes: 
- TGM controller
- Custom wiring loom
- Calibration for sports/racing applications, switchable auto/sequential
- Reverse lamp relay
- Cooling fan control output. From £2100
Optional extras:
- Custom calibration to suit individual car applications and driver demands,
- Push button steering wheel controls for sequential feature
- Omex engine management systems to complete the power train
- Digital display unit with RPM’s, temperatures, gear selection and other user configurable settings
- CAN link

John Cockburn wins with Omex 710 and ACR Dyno Tuning
Ready just in time for round two of the British Off Road Championship, ACR Ltd supplied and calibrated the latest Omex 710 management system on the Tomcat Motorsport supported Range Rover.
Powered by an almost new TVR Griffith 500 HC engine which TVR quote over 360 BHP for, our test bed revealed what has long been suspected, that 248 BHP is more like what the 500 HC unit produces in reality!
After careful mapping of ignition and fuelling, power and torque were up by nearly 8% over standard figures with the 710, mainly as a result of the elimination of the air flow meter. However, as John found out, there is more to how an engine performs than the peak figures. The Omex 710 enables accurate programming: fuel and ignition maps at every point, and precise control of transients such as acceleration fuelling means crisp, clean throttle response right across the rev range.
As such, John was able to win outright his Super Production Class convincingly, despite taking a maximum on one run thanks to a broken shaft in the rear axle.
The Range Rover is a flying test bed for a future new vehicle in which John intends to put to good effect the full throttle gear shift, 16 channel data logging and many other advanced features included in the 710 package. So watch out how John performs as his test bed comes together this season!

NEWS UPDATE JANUARY 2005
Happy New Year to everyone! Hope you have recovered from the seasonal excesses and are raring to go. For those of you who have time to sit down, FPX 391H features on front cover of February issue of 'Land Rover World' as HIDDEN TALENT. The article AIRBORN was written by Kevin Baldwin and shows some superb pictures by photographer Wayne Mitchelson!
Congratulations go to John Morgan, winner of an ACR Stage2 CR 9:1 cylinder head in Land Rover Monthly competition sponsored by ACR. Good luck to John in his Land Rover rebuild project!
All @ ACR January 2005
NEWS UPDATE NOVEMBER 2004
Yep, we entered the Welsh Hill Rally and FPX 391H got out (Vinny Jones as co-driver). Not having had time for testing and setting up, no spares and no experience of the car, we set off (in true motor sport fashion) into the forests of North Wales. Despite a major navigational mishap, the first few stages went reasonably well, although the car was difficult to drive on the fast forest sections (we will most likely revert to normal diff on the front rather than Quaife). The car kept cool and the suspension most certainly soaked up the rough terrain. Unfortunately, on stage 7 we knocked an oil pipe and lost pressure. So that was us out!
However, Tim Dilworth and Anthony Brinkman triumphed again in the Simbugghini (now belonging to Dave Simmonite) and took 1st overall.
Congratulations go to Hugh Haines and Peter Phillips who won The Hill Rally Championship 2004 with their Bowler Wild Cat. Chris Ratter and Tim Curron won Class C with their 300 Tdi 90” (with ACR tuning). Well done Chris and Tim!
On the British Off Road Championship, Richard Kershaw and Graham Broadbent yet again dominated the Series with their Amaterati and took 1st overall. Great stuff! However, 2nd place was taken by the expertly driven 88” Tomcat of John Cockburn, who has to be the Driver of the Season! (credit also to George Bream, John’s co-driver for the Hill Rally Series)
Back in the workshop we have been busy on the V8 Top Hat Liner system. This liner sorts out all the problems with these later engines and is a much more reliable solution than using one of the rapidly diminishing stocks of new standard Rover blocks.
Finally, testing is now underway on a series of new cam profiles we are developing for the Power Plus tuning system, so if you fancy even more power from these engines watch out for News here!

NEWS UPDATE AUGUST 2004
It’s finally on the road! FPX 391H is now back in action. After an 18 month total rebuild my Series 11A 88 passed its MOT and turned its wheels once again.
At the end of 2002 it was taken off the road, having been in my ownership since 1990, as daily transport, abused offroader, tow truck and test bed for many new ACR products. Having covered 379000 miles and 32 winters, the bulkhead was definitely past its best although the chassis and running gear were in good order!
The plan was to retain as much of the original vehicle as possible yet transform it into a hill rally spec racer to modified production class regulations, which means original silhouette and chassis, a standard Land Rover engine. But axles, suspension gearbox and many other parts are free. The final specification results in a Freelander V6 petrol engine mated to a much modified Jatco / Rover 5 speed Autobox. Suspension is King 14” travel coilover units mounted to Disco Mk2 axles, making this one of the more modified vehicles in its class.
Its first competitive event is expected to be the Welsh Hill Rally in October, which leaves us with two months to set up the suspension, and test out the rest of the Land Rover ready for the forests and mud of North Wales!

Its finally here!
Welcome to our new web site. We hope that
you find this informative
and easy to use. Please let us know
if you have any difficulties
or comments regarding our site.
The last 12 months have been very busy indeed. We have
installed
a new engine test facility which will serve several
purposes. Firstly
it will enable us to develop new products
for our Power Plus © range
of performance parts for Land Rover
owners, without having to use
outside facilities, And secondly
we now offer a new service for
customers who require engines
setting up for motor sport and performance
applications.
In 2003 we set up and calibrated an Omex programmable
engine management system
for Tim Dilworth and Anthony
Brinkman for their 4.6 L Rover V 8 powered Simbuggini
off
road racer. Over the season They went on to claim the national
Hill Rally
Championship out-right, with some astonishing
performances, like winning in Scotland
by over 9 minutes.
2004 sees The Dilworth / Brinkman team building a brand
new
car to international race specifications.
For this season we have set up the massively powerful 5.0 L
Wildcat V8 for Neil
Davey, who is competing in the MSA Off Road
Championship, and on the first round
scored third overall.
We have supplied engines for several new projects which will be
ready for next
season. This includes our own new off road racer
which will be powered by the
4 camshaft KV6 engine as used in
the bigger Land Rover Freelander models. Watch
this page for
more updates. Please let us know if you have interesting news
regarding
the use of our products or services. We would be glad
to publish the details
here.
