Digsy Posted July 23, 2001 Author Share Posted July 23, 2001 I called JIC on Friday to get some feedback on my queries. Unfortunately their conversions guy has been off sick for a while so they didn't have any answers. I'll try them again this Friday... Does anyone know who they use for their conversion work?

francesca Posted July 23, 2001 Share Posted July 23, 2001 Still can't find my notebook that I wrote the original instructions in which is driving me nuts - soon as I stop searching it will re-appear in the first place I looked..aarrggh Anyway - spoke to Tim & Steve, they gave me the phone number of the guy that did the conversion, but when I rang & said basically 'can you run that by me again' he was fairly aghast & said definitely NOT a DIY job, need to take it in or pull it out & post it..now I know when I spoke to whoever before it really didn't sound like rocket science, i just didn't get round to it 'cos of the snow etc, yes OK I know... SO - rang Tim again & asked WT* & he just said take it in & we'll cover any costs! Said place is I think in Buckingham. Apparently problem is something to do with the de-limiter being by the gearbox & not behind the dash, so when they do the odo the signal gets divided twice as they are not aware of original slowing down of signal - I'm sorry this is not very technical, I'm not au fait with the correct terms! Seems as if one person does the de-limiting & another the speedo/odo conversion which seems a bit odd. I shall continue to hunt for instructions & maybe take car to be fixed if I get time, so will keep you posted. It was all a bit vague but they probably didn't think I'd understand anyway!

Paul Booth Posted July 23, 2001 Share Posted July 23, 2001 S'ok. It helps to know where to start from. What are the characteristics of a car hitting the limitation barrier? Does anyone know the answer to this? (Edited by Paul Booth at 6:26 pm on July 23, 2001) Quote Link to comment Share on other sites More sharing options...
Phil Wall Posted July 23, 2001 Share Posted July 23, 2001 Andy Metcalfe should be able to give a description as he has only had his car a few weeks and just had the delimit done. He had found the limit several times that I know of. He may be working a way this week. If he does not pick up this thread, I will ask him to post next time I see him.

Guest Ash Posted July 23, 2001 Share Posted July 23, 2001 I lost the direction of this thread. What do you mean by "limitation barrier"? Are we still talking here about the top speed limit on the J-spec car? Yours, J Quote Link to comment Share on other sites More sharing options...
Phil Wall Posted July 23, 2001 Share Posted July 23, 2001 That's what I assumed we were discussing. Quote Link to comment Share on other sites More sharing options...

While mine is supposed to be de-limited, getting it passed a displayed 120 is near impossible; well, it struggles beyond. If I know what to look for, and we get the specs for a good conversion, I can do the work to ensure mine is done correctly. Quote Link to comment Share on other sites More sharing options...
Guest Ash Posted July 24, 2001 Share Posted July 24, 2001 About 120 mph the car will seem to cut out for an instant then come back on power again. Which will repeat until you back off below the speed-cut threshhold. The way to defeat it is to clamp the frequency of the speed-signal being fed to the ECU. The easiest way IMO is to simply fit the HKS SLD. There are two types depending upon whether the car is manual or auto. Yours, J Quote Link to comment Share on other sites More sharing options...
Paul Booth Posted July 24, 2001 Share Posted July 24, 2001 Nope, it's not that. It just runs out of wind. It will keep accelerating but veeeery slowly. I was worrying about engine ECUs getting confused by badly routed information. If I can find out who's done what and how to mine, I can reset it to near original and fit the HKS jobby. Do you know pricing and availability? Quote Link to comment Share on other sites More sharing options...
Branners Posted July 24, 2001 Share Posted July 24, 2001 We sell the HKS SLD in Shop!! As with most HKS parts it should be pretty much immediately available. JB Shop!! Quote Link to comment Share on other sites More sharing options...

Syed Shah Posted July 25, 2001 Share Posted July 25, 2001 The J-spec limit barrier is 180kph (112mph). The JIC only trick it into reading mph, so Steve told me that technically the cars are limited to 180mph instead of kph. By the way, I would reccomend the HKS part the best.

Digsy Posted July 25, 2001 Author Share Posted July 25, 2001 So it sounds like JIC apply a "divided" signal to the ECU. That's what I originally thought but I'll call them myself on tomorrow. Without wishing to slander JIC, the concensus here seems to be that this is not the best way to delimit a car. Darren Quote Link to comment Share on other sites More sharing options...
Phil Posted July 25, 2001 Share Posted July 25, 2001 I've had two cars from JIC though, both imported and derestricted by them, and they both happily run to 170mph+ on the speedo. Perhaps the car was owned previosuly in the UK and someone else had a go or maybe they've changed the people who do the delimiting? Quote Link to comment Share on other sites More sharing options...
Digsy Posted July 25, 2001 Author Share Posted July 25, 2001 Phil, No odd behaviour from the car at all? Strange Auto box operation? Warning lights? Error codes? Nothing? I checked out the Smartgroups site the other day and someone else was complaining about a dodgy speedo conversion / delimiting job...
