Hi Marc,

Now I got this mod drilled in my head, I want to find-out more information about it if I may

I can get this unit here in Australia and I can have it installed, dyno-tuned and all that (the fitting and dyno tuning is gonna cost me double the price of the actual apex'i )

I need to know what was your fuel consumption like before this mod and after? since you've been running with it for quite a while.

What I'm trying to establish, is the benefits to fuel consumption should I go down this path which will in turn help me recover some of the money am gonna spend on this mod (which looks like over $1000AUS!!!)

Power and performance increase are secondary targets for me doing this mod. My exy is running rich 11:1 at the moment and I want/need to fix this problem and if this is gonna give me more power, then that'll be a bonus

Look forward to your reply.

Thanks Terranismo,

How much of a drop in fuel consumption are we talking about here?

What is the fuel:air ratio setting you have set the apex'i to?

Nah, this forum is going OK, spring is just starting there, so they must be all out swapping winter tyres to summer ones LOL

Thanks for the advice Marc.

So, you're saying that the fuel saving is not that significant to justify spending that sort of money of this mod?

I know that Nissan has set the stock exy to run rich to minimize the chances of warranty claims, but what are the risks of running lean?

Since the extractors and exhaust system upgrade I stay more often on higher revs That is at the lights and on the highway, but majority of my driving is between 2,500-3,500RPM

The above price I quoted includes a dyno tune, has yours been dynoed at all? If yes, what was the confirmed power gain?

Wow Terranimso, that is really impressive!!

Is that at the wheels reading after the nitro experiment?

Do you have the dyno charts for us to look at?

Excellent stuff!

Marc, I am now looking at getting the Apexi for my exy (that sounded good LOL) to correct the running rich problem I am having, but when I started to look for to aqcuire one I noticed that there is a new release product that was released after the Apexi SAFC II, called the APEXI AFC NEO which seems to do everything the SAFCII did and offer more.

Do you know anything about it and if it can be hooked-up to the exy in the same way the SAFCII?

Also, I have been getting conflicting recommendations about the use of the Apexi due to the fact that it doesn't offer timing advance capabilities which other similar devices (like eManage and others) can offer.

Is timing advance capability really needed, considering that the TA can be done as a one off setting or do I need to look to have the TA value adjusted for all RPM ranges?

Thanks Marc. I have decided to go with the Unichip that controls both timing and fuel:air ratios. Will update you guys when it is all fitted and dyno tuned.
