If anyones got more light to shed on the system that was running lean I would be gratefull, just that I have a full Janspeed and i'd like to think it was all hunky dory Really need to take the day of and get a tms remap one of these days

[Jay05]

LY25MAX-do you have the "full" system meaning the sports cat section? if so whats the sound like and do you have any pictures? would be great to see and even better if you had a sound clip? im interested in getting the hole thing aswell meaning the backbox-£375 + the sports cat section £275 also how much dod you pay if you dont mind me asking. thanks alot

[LY25MAX]

Yeah, its the full system. Sounds Doesnt annoy me on long journeys either. I have an MVI video clip if anyone can host it? Whats your email, i'll send it over anyway. I think the best price ive seen is directly from Janspeed.

looks very good im liking the fact that its fully polished aswell, also PM sent so you can send the vid clip to my email. thanks mate

whose is the blue na vx at the national which towards the end of the day, had Thorney plugging the laptop into its internals to find that it was running lean. The front number plate had half a union jack on it. I think it was running a janspeed system, and the conculsion of the test was, get rid of the exaust, its not very good for the engine. Well, any engine running too lean isn't exacty happy.

Could it not be remapped to correct the fueling for a Janspeed? Perhaps it needs the map tuning on a rolling road? Perhaps the stock TMS maps are only suited to Milltek setups?

Getting a map that works well for a Janspeed has to be cheaper than buying a new exhaust and the owner gets to keep the aspects of the Janspeed that made them choose it in the first place.

Ben, you've missed the point. The car was running on a standard map not a TMS one. This particular exhaust was making the car run lean with potentially disastrous consequences, Milltek (and others) exhausts bolt straight onto the car and give extra performance with no such risks so there is inherently a problem either with that particular exhaust or with the whole design (which seems to be the case as there are several people with the same problem with the same exhaust). It has nothing to do with ECU maps. There is no harm in looking for the cheapest option but remember sometimes cheap does indeed = crap, a badly designed exhaust can kill an engine if its bad enough and running lean is a very good way of doing that. The reason why the owner asked to take a picture of the tech2 read out was to prove that he wasn't making it up, all I did was run a diagnositic on the car and show what the check engine light was showing that is all. Indeed I actually said to the owner to get rid of the exhaust, buy anything else including going back to stock as running lean was bad. We (and Courtenay and numerous dealers) have fitted over 120 of these exhausts to NA's and NONE have generated a problem of this kind. That (IMO) speaks volumes for the design and quality of the NA system.

Ah! OK, got the wrong end of the stick there. Just out of curiosity, could a map be developed to correct the fueling?

I don't think I'd buy a Janspeed for an NA VX anyway after seeing the alternatives but I assume that it's only the full Janspeed system that exhibits this problem?

How does the full Piper fair with regard to fueling?

Is he still suffering from a dodgy lambda sensor or was that resolved? IIRC, it was damaged during exhaust installation about 2 years ago and he's been suffereing all sorts of problems since then depite it being 'repaired'.

[Thorney]

Not sure, it does sound like a sensor issue and theres no reason why the exhaust should cause such problems, however I think the issue was that he was pissed off that it was still causing an issue after all this time and was being given the run a round (hence the request to take a picture of the tech2 read out). Ben, yes, assuming its not a sensor malfunctioning then the ECU can be remapped to allow for things like decats etc but the point really should be why should you need to.

[LY25MAX]

Its always been the plan to get a tms remap at some stage- looks like i'll have to get it looked at sooner. Would you be able to remap my car and check for any problems at the same time John? If there is any problems would you then be able to sort them?

[Thorney]

In short, yes. It would depend on what the problems are and whtehr any parts were needed, we keep most in stock but you never know but we've not found an issue yet we can't fix ECU maps are only ever done when we're happy everything is hunky dory.

[LY25MAX]

Now the biggest problem i've got is finding the time to get down saaf. Do you open on saturdays?

[Thorney]

Only if I can't avoid it.

[LY25MAX]

No worries then, im away a lot with work over the next month- might have to blag an extra day off somewhere You'll be getting a call soon then Mr T.
