"Piggy Back" ECU
Hey all,
Just wanted to discuss about installing an engine management system into an X-trail. After installing the Hi-Tech Muffler exhaust (Thanks Lambros!) the fuel is running very rich. The guys at C&V performance recommended I get a piggy back ECU to correct that problem and to also increase power by tuning it. Does anyone have experience in this?? I am currently looking at the Haltech Interceptor. From what I have read it seems to be the best option. Is anyone else interested in getting one? Do I hear a group install??
Let me know
Paul.

Re: "Piggy Back" ECU
Hi Paul,
To be honest, I didn't hear about the Haltech piggy back ECU until you and Lambros told me about it.
I have read all the information concerning this mod and it sure does sound like the most sensible way to go once you start doing performance mods, but I think it's a bit early to have it done now, just by having the "twins"
The exy sure does run a bit rich (can't say too rich though) and I have asked the dealer to look at what can be done in this regard from their end.
I have contacted Haltech accordingly and was informed that a piggy back ECU (called Interceptor) will be released early next year and they will let me know when it's available.
This means that there are bound to be some bugs with it before it is tested accordingly and everything is bedded down.
In the meantime, the piggy back ECU that has been in the market for quite some time and used widely by Nissan Performance seekers is the APEXI SAFCII unit.
This one has been proven to work with the exy and the results are proven too.
Read all about it HERE
For those interested to read about the Haltech Australian Interceptor, you can find all the information HERE
Group-buy? Good idea, but I think am not ready for it yet, I still have other performance mods in mind before my exy will need the piggy back ECU
P.S. I'm happy that I could help you score the twins and that you're happy with them so far.

Re: "Piggy Back" ECU
UniChip is another one you could consider. I can't guarantee they'll work with our engine management (but I can't see why not) - I had one in my Pulsar SSS and it was enough for the mod's I'd done to it (I would've needed a computer more complex if I'd gone further than exhaust, extractors, cams, and headwork). Fitted price was around $1500, but it may have changed since then. Also the guys in their QR25DE-equipped Almera's (overseas) who have had time to play around with different setups could possibly point you in the right direction. (The UniChip has a different name over there, though)
If you've got some time to read through this site, have a look there: http://www.qr25de.net

Re: "Piggy Back" ECU
Blackxtrailgt,
I was just curious but as I thought it was to cheap to give you the goods. I'm happy with the exy performance as is with a kid in the back even if I look like accelerating hard I get the look from the cook
cheers Dave

Re: "Piggy Back" ECU
For the electronics DIY people try THIS
This does the same job as decribed above but quite a bit more accurately and permanently. This would require a professional with dyno to adjust. It may even be possible to cause engine damage if you just messed around with it.
This is basically exacly what those Piggy Back ECUs are, but just a lot cheaper.
There's also a bunch of other stuff at Jaycar that's pretty interesting: Browse for Kits, Automotive
Check the Digital Speedo adjuster if you've fitted big tyres!
