I'm now about to test the 3rd different plug in module, it is RaceChip and my car us an n18 r58..
If im correct does THE RaceChip plug into BOTH tmap amd map sensors??? Or does it plug in like the nm module into the mafs and map sensor ( infront of throttlebody in plastic boost tube )..
i wanna make sure because the mafs plug and rear tmap BOTH would fit ..
any help is always much appreciated !
BTW after I test this RaceChip I will make a post discussing the jb+,nm module and the RaceChip and which does whst and how they all perform and imo which is better..

 

For any plug in module, I wouldn't any cooler than OEM JCW spark plugs. With spark plugs, you want the heat range to allow for self cleaning, but not too low that they start to foul. I don't think any of those plug in module alter the timing enough to warrant anything lower than OEM JCW spec.

 

I run ngkR jcw plugs because mine Is a jcw engine and running lots of extra boost and a tad thinner headgasket for a little more compression.
I meant what plugs do I plug the RaceChip into lol not what sparkplugs I need..
But thx fir the heads up..
I was told go 2x step colder but imo that's wayyy over kill. With the nm module I was making 24psi and I have a ported head and great flowing mods and run ONLY 93oct plus a little octane booster.. I've never experienced any pinging or knock and my afr at max boost near redline at its most lean is 12.5..

here's my engine as of now.

 

I guess I should have been more clear..
what sensors do I plug the RaceChip in to ? Is it the map and tmap because I found a video where the guy says to use those 2x sensors to plug it into.. buuuuut the nm module had the exact same looking harness and it plugged into the mafs and the map sensors ( one in plastic boost tube )..
I emailed RaceChip but who knows when or if theyll respond. I just wanna make sure I plug it into the correct spot and not screw it up.

 

LOL, derpy derp...

I don't like their product, mostly because they don't have specific installation instructions for each application they support. Only generic installation instructions.

And, here you go:

 

that's not even the harness I have, mine only has 2x connections so wtf ???
see , every installation instructions I find are different, how tf can that be .? I'm willing to bet dude who sold it to me just didnt really know , when it probably fits who tf knows what...

My guess would be the manifold pressure sensor and the MAF. I am also under the belief that all those connectors are different, so it should only plug in one way.

 

im pretty sure the mafs plug is basicallythe same as the tmap sensorin the boost tube but i may be wrong..
what I'm worried about is though it should plug into those 2x , it doesn't fit the rear map sensor. It is for euro spec n18s amd I guess they didn't run a mafs in some engines in certain places , even the proof of purchase is in Euros or something. I'm hesitant to try and make it fit.. I could just cut out this bar in the map sensor plug and then it would fit but im worried that if it's for a different ecu than we have here in the states it might bunk something out. So I gotta do some more research and maybe it might work with a few modifications or I might need to try and purchase the USA spec 3x lead wire harness for it IF the module would function with that or if it's tune is set to alter only the 2x sensors not 3x..
lol I opened a can of worms with this one..

 

Lol OK so hypothetically the race chip plugs into BPTH map sensors..
then , what IF I put a jb+ onto the mafs then also ??? Would it STACK the targeted added boost numbers or i wonder ?
because what these tuner box's do is basically a one off of what tuners change . So I wonder if that'd be possible and if it would actually help add MORE boost than just using 1x or the other.. I mean , there are ones that plug into and alter all 3x sensors so why wouldn't a jb+ work along with this RaceChip ??? Lol I'm curious...

 

I wouldn’t do that, but you’re not me. If the plan is to go full rebuild on the engine, I might be tempted to test it out.
