Blitz R Fit For Nm35

[slippylotion]

Hey guys

Just looking into something easy to adjust the factory fuel maps to lean it a tad from the usual rich factory settings.

Came across the Blitz R Fit and looks reasonable. Anyone had any experience with these units? You can order it set up for the Nm35 to make it easier. Looks like the price is around $450 delivered.

I'm not worried about adjusting the ignition for extra power, just the fuel for a bit more ecconomy. This will also give a tad more power with leaner maps so that'll do me.

So what are your thoughts or do you know of another unit under $500 to easily do this other than Emanage?

Cheers guys

Fcon iS can be had for under $500

Lean tuning on boost is not a good idea, cruise is ok to some extent but I would get a temp sensor in the manifold just to be sure before leaning it out too much. Have you checked afr's? I thought our ecu was fairly good until boost is increased.

Perhaps you could dump the o2 sensor and fiddle with lowering the fuel pressure if you have a wideband.

You also need some way of clamping the AFM voltage as any airflow gains and you will hit a wall.

I haven't had a wideband on it yet. A mate that tunes has one so I'll run it one day soon and see what it does. Im assuming like all Nissan turbo cars it runs in the 10's afr under boost, this can safely been leaned out to 12:1 with out any dramas.

Im sure i have read before someone on here plays with the AFM voltage to do a similar thing, who is he and how is he doing it exactly?

Cheers

Leon (Commsman) does it, and he's posted a big explanation recently. If you do a search you'll find it, but it should only be back a page or two. Think it was in the G-Zone thread maybe?
