  1. HI Erik, Wow, sorry for the late reply ! The forum did NOT send me an e-mail to notify me of your reply, even though I did ask for daily updates on this thread ! GRRRR ! 😕 Yes nothing beats a real ECU indeed ! But 10 years ago when I did this little ECU reader, I had absolutely zero money. I was doing it mostly to keep me occupied as I was job less at the time... but zero money to put into the project. So an ECU simulator using an 8 bit MCU worth just a few Euros, was much better than nothing : at least it allowed me trouble-shoot the routines that receive the data. Make it w
  2. Hi Erik, You didn't give the source files for your program. That would be the interesting bit. I am particularly interested in the protocol handler routines. 10 years ago I too had some fun designing a custom hardware solution. Records also on an SD card in .CSV format. Made an ECU simulator to go with it, so I can send frames to the ECU reader, to feed it with some data, worked fine on the bench... but when I tried it on a friend's Esprit once (only had one shot at it sadly), I could not get my bloody reader to establish contact with the car, grrr... though the little
  3. LOL ! Could also be a simple PROM or a fancy EEPROM.. but looking closely it looks like it's an old fashioned ceramic package so yes, most likely an EPROM. Just need to lift the sticker to know exactly what chip it is... Enough sarcasm though ! ^^ I think the OP was more interested in knowing what company this non-OEM chip is from, so as to know its technical specs, feedback on it etc... rather than just "it's some random obscure 0.9 bar boost chip, made by some random obscure unknown bloke some time somewhere "... LOL ! Not putting a date, firmware revision and compan
  4. Yes it looks promising, thus far, looking forward to see its guts, crack it open ! 🙂 But do so extremely gently of course... With some luck the body will just be held together with clips, with less luck it will be glued or ultrasonically welded. In this case you need to "Dremel" the joint/weld with a small cutting disc, being careful not to penetrate the plastic body by more than the thickness of the enclosure... the electronic circuit board will probably be right behind and could get easily damaged. Set the speed of the Dremel as low as is possible as long as it can still cut the plasti
  5. Well it depends what's wrong with your clock ?! If you mean that the LCD display itself is damaged / "leaky", all you can do is replace it. However if the LCD display itself is good, and you suspect it's just the electronic part of the clock that's not working right... then depending on how it's made (never torn one apart before), might be repairable since it's all school electronics... the kind of thing I like to work on and fix. However if the mechanical construction makes likely that it would get damaged while trying to take it apart, and/or if all there is to see inside is a blob
  6. You are welcome. Just for correctness... I think I got carried away when I stated that the regulator "had" to be on fuel rail itself. The last 3 cars I had, a Renault 21 TXi Quadra, had the regulator on the rail, which is actually very practical when I had to replace on of them : superb access, only one hose connected to it, and then just pops off ! However before that I had a Renault 21 GTX (same engine but 8 valve cylinder head not 12V like the TXi variant) and now I think about it, on the GTX the regulator, though it was indeed real close to the rail, a couple inches at best, was act
  7. Hi Martin, Like most (all ?) fuel injected engines, the regulator is mounted directly somewhere on the fuel rail. In the Esprit, it's more precisely mounted on the rear-most end of the rail. I circled it in green in the two pictures below. On the second picture, the charge cooler has been removed, making it much easier to see the fuel regulator... Hope that helps. Vincent Trouilliez
  8. I don' t have particular knowledge of Blaupunkt, but I used to see their stereos as OEM fitment in mundane cars in the '80 and early 90's, over here in Frog land, and "epitome of Engineering" never came to my mind about these units, to be honest ?! Or maybe it's just that Blaupunkt marketing department managed to generate a feeling of an upmarket brand, in the USA ? But maybe I didn't have the full picture back then, maybe they did make high-end units as well, I wouldn't know. What they do as of today doesn't look any better than the ordinary "in your face" stereos, that every m
  9. Ohhhhhhhhhhhh......... The SE is my favorite model, it really hurts to see the poor girl in such a state ! And he wants 50K Euros for that ? I will offer 50 Euros : the price of the steering wheel and Lotus badge at the front, which look like they are pretty much the only parts that could be salvaged from this wreck ... Says "unique example" , well I bloody hope so, for the sake of Esprits ! I know I know... to each their own as usual, and I am sure someone will find it beautiful and will be overjoyed to pay 50K for this chef d'oeuvre.
  10. OK, so from you just said, looks like the compressor is good (gives enough pressure), and the clutch works too, and the fans work as well. So basically all you need to figure out is why the clutch is not being powered... so again, get your multimeter out, and print the diagram, and start troubleshooting ! ;-) Sorry but not much else I can tell you... I can't do it for you... you have the car not me ;-) Yeah electrical problems are a pain, but the more you do it the easier it becomes... and the hot weather is supposed to motivate you, I would think ! ;-) Looking more close
  11. Sounds like it's a regular 88 Turbo, not an SE.. but that is easy enough to figure out, just send a few pics of the car, exterior, interior and engine bay ! ;-) If it's an SE you will find the big red intercooler sitting on the engine, to start with ! :-)
  12. BTW, something totally unrelated... your avatar says you have an '88 SE ?! Either it's a typo, or you managed to lay your hands on an early prototype of some sort ?! Thought the SE didn't hit the market until mid-1989 from memory...
  13. If you don't already have it, here is a copy of the electrical diagram for the A/C (and heating and cooling) circuit. Just start at the beginning : from the compressor/clutch then move upstream progressively, one step at time, methodically. So first, engine stopped, run a wire from the positive terminal of the battery , and feed the clutch directly, to see/hear if it engages or not ! If it does, then the problem is upstream, so start up the engine and turn the A/C on and poke around 'til you find the faulty part ! ;-) Engine running means be careful where you put your hands
  14. OK, so looks like you might be lucky and the A/C is fine and it's just an electrical problem ! Time to get your multimeter out then, and go poking around, armed with the electrical diagrams ! ;-) Can't help you with details as I don't even have an Esprit, but it's just basic electrical troubleshooting, so should not be too difficult/long to diagnose, I would think ! ... of course accessibility might get in the way of concerned electrical components, I wouldn't know, short of a car. Others will be able to help I am sure. But if you already suspect a relay or whatever, and ha
  15. Hi Carl, Not an expert on the Esprit A/C, but it works the same as any other car so... what I learned on my daily runner while taking its A/C apart, along with the practical advice I was given by an actual A/C specialist/independent, might still be helpful. If the system is checked and found to be charged, then at least we know that there is enough refrigerant left in the system and that it is not leaking.. otherwise the refrigerant would have disappeared long ago. So that also means that the fragile/exposed/prone to failure condenser is not leaking either, which is good news
