Boost woes.. Lots of trouble Usually Serious

Marcus @ PUK racing is adamant the car running 280bhp @ 0.8 bar is still not right. Unfortunately Falkland adamant that car is running fine even though the car is putting out barely more than standard bhp and @ less boost. I could raise the bar but PUK reckon the set-up needs to be adjusted first.. but surely retrograding standard inkectors etc etc would be a timely and expensive exercise.

At least it's a step in the right direction but this is frustrating time in the project. Sketchy information from previous owner is not helping..!

Maybe freeware is the solution - if I learn how to use it? Will speak with Dermot as to where we go from here..

FreeScan is a windows-based program that is able to communicate with the ECU which controls all all 4 cylinder Lotus Esprit models built between 1989-1999 (SE, S4, S4s, GT3). These cars were all fitted with the GM Fuel-Injection. This software can help with tracing problems with your Esprit including reading internal error codes and also making sure everything in running as it should. Many Esprits are currently running at less than 100%, don't let yours be one of them. This software is a must for all Esprit owners with GM Fuel Injection.

Requirements: FreeScan runs under the Windows 95, 98 or NT4 operating systems and needs 800 x 600 minimum display resolution and one free serial port. It is recommended to have a 90 MHz or better Pentium and at least 32 MB of RAM. You will also need an interface cable that connects your PC to the GM ALDL port. All you need to run FreeScan is available at the LEW-Shop.

The data is in TTL (i.e. 5V), bi-directional (half-duplex) format and runs at 8192bps. The Installer we are using was downloaded from the originator Andy Whittaker at:www.andywhittaker.com/ecu/download.htm

The source code has now also been made available at :http://sourceforge.net/projects/freescan/
Lotus Esprit World can supply you with everything you need to communicate with your Esprits ECU via your laptop.
