jim Posted August 1, 2011 Share Posted August 1, 2011 The other half has a 2.0 dci Qashqai, and we were wondering about the benefits (or not) of plugging in one of these diesel tuning chips you see advertised in Autocar etc. While we are not looking for a major performance hike, it would be nice if we could get some of the claimed improvements (smoother torque curve etc.) and perhaps a bit of an improvement in the mpg. Anyone had any experience of these chips? Part of the problem is choosing between the variety available - all of them include testimonials from lots of "satisfied customers", but not sure whether to believe them or not. Here are some examples. Are these reputable companies? All advice will be welcomed. http://www.chipexpress.com/products/1615/ http://www.tdi-tuning.co.uk/car_and_van ... _P608.html http://www.diesel-performance.co.uk/sys ... hp?id=1151 http://www.bhpplus.co.uk/Speedhawk-Dies ...

Neilp Posted August 1, 2011 Share Posted August 1, 2011 probably cheaper and more safer to get it mapped on a rolling road tbh matey. At least the engines working safely that way Quote Link to comment Share on other sites More sharing options...

Are the costs for a re-map similar to these piggy-back chips? Do you know anybody in our area that would do that kind of work? Quote Link to comment Share on other sites More sharing options...
Stew Posted August 1, 2011 Share Posted August 1, 2011 I have a DTUK PDI in my Navara. Been faultless and it's set for power. Loads of settings and a quality bit of kit. Might dd a CRD at some point too.... Quote Link to comment Share on other sites More sharing options...

Neilp Posted August 1, 2011 Share Posted August 1, 2011 Speak to Falcon Performance. They are well experienced at doing diesel re-maps. Yes, but Middlesborough is a fair hike for me! i spoke to rs tuning about remapping the xc90 and they were pretty confident about it. Thats in leeds so around a 3 hour drive. Theres places up here like wallace performance, and another place i cant remember the name of, who do alot of work on evo's and impreza's etc who may be worth dropping a phonecall to Quote Link to comment Share on other sites More sharing options...
varley16 Posted August 1, 2011 Share Posted August 1, 2011 http://www.pro-bitz.com/eshop/ i had one of these on my 2.0 mondeo tdci. improved performance but i mainly used it for fuel as i was doin 100 miles a day, so going from stoke to derby every day i was averaging about 60 MPG, and a good day with granny driving i hit 70 MPG. i had a mate who recommended it after he had one on his bmw, and he was amazed by the reults.

Hmmm - that's a strong recommendation, but these chips are considerably cheaper than the ones I posted about. I always reckon you only get what you pay for, and the low price of these would worry me a bit. Quote Link to comment Share on other sites More sharing options...
Stew Posted August 1, 2011 Share Posted August 1, 2011 I was the same Jim. I did a bit of research to find what worked with my car (Euro 4 Navara Auto) as a lot of chips didn't work too well with the euro 4 navara causing limp mode to be engaged. Mine has been on for 6 months now and I've had no issues. MPG has gone up about 30% but with the temperature rising this could account for a proportion of that in fairness. The one I'm running has a good rep and proven results. The owner of DTUK has a navara too and did dyno testing. Quote Link to comment Share on other sites More sharing options...

Yes - I think I need to do a bit more research before committing to a particular product. Might give DTUK a ring tomorrow. Quote Link to comment Share on other sites More sharing options...

Stew Posted August 1, 2011 Share Posted August 1, 2011 What sensor does the pro bitz one work off of? How does it work? Jim, you checked the quashqai forum? I'm not sure if it's any good - I just found it when I wanted to confirm tyre sizes on my sisters one! Quote Link to comment Share on other sites More sharing options...

Opinions varied pretty much as they have here. Quote Link to comment Share on other sites More sharing options...
Ricey Posted August 1, 2011 Share Posted August 1, 2011 on phone so cant get linky for you but search for my 'power dropping out on diesel' thread. mine was 250 quid ....lasted 12 months but you get what you pay for I guess Quote Link to comment Share on other sites More sharing options...
lorryman100 Posted August 1, 2011 Share Posted August 1, 2011 The biggest worry about these after market plug in chips is that they are generic in that all they basically do is fool the ecu into pumping more fuel into the cylinders by raising the Fuel rail pressure and the fuel regulator on the pump. They do not match up boost with fuel resulting in more black exhaust (unburnt fuel) or take into account dealer ecu updates. I have had diesels forever and you cannot beat a personal remap by a company who specialise/invest thousands of pounds/hours in producing non generic remaps. I currently have a 2009 Defender 110 which has a remap from a company called Alive tuning (Landrover specialists) who do bespoke remaps based individually on the OEM fuel map stored in the ecu, resulting in more BHP/Torque and everything is balanced with no flat spots meaning a clean burn with no noticeable exhaust smoke even under heavy acceleration. I have a 30% increase in BHP/Torque and now get 32mpg instead of 26mpg driving the same way and it comes with an interface which allows me to re install the original map file for dealer visits, so my advice would be to go for a remap rather than a plug in chip, it's safer for your engine.

Maybe a remap is the safer route to go down. Quote Link to comment Share on other sites More sharing options...
Stew Posted August 2, 2011 Share Posted August 2, 2011 Remap is the best route for sure. I went the cheat route on a product that had been tested and the multiple maps tweaked to my car. Quote Link to comment Share on other sites More sharing options...
Ricey Posted August 2, 2011 Share Posted August 2, 2011 Almost all if the websites I researched on said to go remap.....problem was my car was still under warranty and I wanted to be able to unplug it. As far as insurance premium went .......20 quid extra Quote Link to comment Share on other sites More sharing options...
jim Posted August 2, 2011 Author Share Posted August 2, 2011 Looks like I'll just have to find somewhere in Central Scotland that does remaps for Nissans. Thanks for all the replies, folks. Quote Link to comment Share on other sites More sharing options...

varley16 Posted August 2, 2011 Share Posted August 2, 2011 Remap is best way, the Mondeo I had is a very basic diesel engine, so the probitz box I had was cheap and cheerful, but as you have a far more modern car then I wouldn't go for a cheaper box, may aswell be safe with a proven remap for your car.

jim Posted August 13, 2011 Author Share Posted August 13, 2011 Quick update on this. Eventually went to Power Tune in Motherwell for a remap. Joe did an excellent job, and explained everything very clearly before and afterwards. The cost was very reasonable, and a lot cheaper than some of the tuning kits I was looking at. The car is transformed, better torque across the rev range, no flat spots now and mpg improved by 10-15%, depending on driving style! All in all, just what I wanted. Cheers for all the advice, guys.
