I have an official PUK Chip #3 for sale. This chip was bought from Marcus (http://freudhoefer.de/lotus/esprit/) previously and I have his permission to sell it. I want to offer it initially for sale privately on LEF. If people are interested in buying it please email me off line at dermot.ohare@chem.ox.ac.uk with a bid price. I consider the PUK Chip #3 to be an excelled upgrade and it has been well reviewed by previous owners. Chip #3 Is based on the improved S4s-Mk5-code but with +18% torque (and similar top end power). It has a revised boost map which gives additional punch in low- and midrange. This version also has better boost control in high boost regions conditions Read the reviews at: http://freudhoefer.de/lotus/esprit/products/chips/4cyl.htm

Dave, Read the manual. You are told to ignore he AFR it is at target figure and not live data. The log is better but you are far from out of the woods. 1. TPS output is terrible, I know it is new but there must be an unstable earth or bad connector somewhere. 2. The fueling is way too lean, bad fuel pump, bad injector, fuel pressure regulator, something is up. 3. You have no ECU boost control, this might be due to the ECU detecting the high coolant temp in that log and shutting it down.

Cheers Dave, Resister Pk1. gone to Ireland.

Dave, Yes do items 1-3. Regarding the TPS. I agree the zero is a bit out. However, if you plot TPS vs. TPS (volts) it is not linear. Multiple voltages return the same %TPS.

David, The 2nd log is much better but you have some serious issues. Some are interrelated so the key is finding the route cause. For example, the you have coolant temps reaching 105 deg (what were the fans doing ?). There is a transition in the log for coolant temp from 73->109 deg within one data point. This could be the coolant sensor of the ECU input circuit. The fueling is all way too lean. The TPS is producing weird outputs at low throttle openings. In your earlier log, fans running all the time is normally the ECU in limp home mode due to a memcal error. My best guess is the ECU/memcal and/or poor earthing of the ECU which is quite common. The ECU has several earth leads and they have to be very good, issue in this area can often lead to intermittent faults. Did the ECU log an error codes, check with Freescan ?

I have a couple of bespoke resistors that someone may find useful. I will offer then on first come basis. Resistor 1. I am sure many of you have noticed that the Delco/Moraine ABS system on the SE and S4, S4s is far from ideal. Have you experience the pedal pressure disappear on under fairly aggressive braking or even under mild braking on a bumpy road in the braking zone. If you upgraded your brakes then the ABS becomes even more intrusive and under ideal dry road conditions you will not get optimum breaking with the ABS on. I copied a design that Mark Weins in California has developed. The best solution to improve brake feel is to disable the ABS solenoids. The way to do this with getting a ABS warning light is to essentially "fake" the ABS computer into thinking the solenoids are still connected. To do this, you can add a simple two-resistor module in place of each of the three solenoids. All other ABS checking functions are still working. I have available a set of 2 of these resistors that I removed from my car before the sale. I only want a few

Yes, sadly lost to the UK. I was surprised there not more interest from the UK. The German guy was the first to see it. The car was running fantastically well and I had spent over 30 hours fully detailing the bodywork. It could not fault it in any way.

Paul, Yes exactly. You just press the new EPROM chip into the holder and then pop it in the ECU. When I first started chip tuning 8 years ago I could not bring myself to desolder the original EPROM from by original memcal knowing that if anything went wrong the car was scrap. That us why I have held on to these for all these years.

yes, car is sold. The buyer paid

I imported this last year from the US and never got round to fitting it. The idea is to do away with all this chip swapping on the memcal. You can dynamically change the code through the usb port on PC. So if anyone wants to go down the chip tuning route on a (SE, S4, S4s, GT3) I would be more than happy to help them set this up on their car. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...em=260392397512

I am having a clear out of all my spare parts as I sold my Esprit today. The first batch of listings have just gone on ebay. More to come in the next few days. Because they are so rare I though I would alert you all to the fact that I have just put 2 memcals for the 4 cylinder GMP4 ECU (SE, S4, S4s, GT3) up for sale on ebay. These are extremely rare and I know of the existence of no others. I came across then about 7-8 years ago and have kept them save until now. If these were ever to fail on a car then it would be the end, that is why I have kept them until now. I have even sent one to a GM ECU specialist to see it they could duplicate the firmware and the knock filter circuit on the board and the they were unable to do as these are unique to the Esprit. One is original, which I can erase and reflash with new code. The other is already modified and ready to take a new chip. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...em=260392228360 http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...em=260392229712

I would be happy to do this. The only problem is that I cannot drive at the moment. I have partially torn my Achilles tendon playing squash. I am in a plastic boot for 4-6 weeks. So we could delay for a bit, or someone drive me to a venue. Of course reading the Freescan manual from cover to cover would be compulsory prior reading !!

I have interest from a German vendor. He wants to come on fly over on Saturday and if car checks out he will pay cash and drive it to the ferry !!! I am just trying to do some due diligence. The chap I spoke to is a trader acting for the vendor who is also coming. The trader has a website which lists UK sourced sports cars including another Esprit (T329 JCL). Anyone know it? http://suchen.mobile.de/fahrzeuge/details....amp;tabNumber=1 My immediate reaction is a scam but it is all checking out so far. One thing I have established today with Barclays is that they cannot verify Euro notes at pay in. It takes 2 weeks so there is no way I am accepting euros if he wants to drive it way on Saturday.

I agree with Bibs. Use the correct oil for the application (engine and gearbox) and decent fuel and you will have no problems. Fuel additives are a total rip-off

All traces of the one I was referring too have been deleted of the Pistonheads and Club Scuderia site, I presume to help stablise the market. It was a well known owner, concours condition, guy needed out of it. I read on one thread he bought it a just over a year ago for
