I've check the official repositories for a basemap close to my setup but have been unsuccessful. Everything I've seen for all-motor is either way off from what I have, or the specs are close but the maps are for sc/turbo applications.

Quick run-down of the important stuff:
82mm LSV with PR3 slugs
GSR head - stock valvetrain
440cc Injectors
Skunk2 Gen1 IM
DC SS 4-2-1 with collector mod

Where should I start? I've got a PLM wideband connected so can tune from there, just need something to get it started up with. Don't want to trailer it to my tuner without first ensuring that I can at least get it to idle properly.

Any and all help is greatly appreciated

 

You could probably start with a GSR or Type R stock.map, then just ajust it for your bigger injectors. That should at least fire it up, then go.from there.

 

Type R would probably be closer, correct? Although, with the PR3 slugs everything I've read puts compression somewhere around 12.6:1. Just don't want to **** this thing up on the first crank

 

With stock cams, and the right injector settings, it should start just fine. But be ready to adjust it to 14.7 soon after it starts

 

That is a misnomer. Not all engines want 14.7 for idle. In fact quite a few of them prefer low 14s... A stock ITR map with one or two degrees of timing pulled will be perfectly fine. Keep idle areas at 16.5* though. Your build is EXTREMELY basic and shouldn't be too far off from the stock ITR map.

 

This was my overall thought, but considering the significant bump in compression ratio I didn't know if it would present a serious issue.

 

Not at idle, and not with stock cams.

 

nobody shares basemaps anymore, its all about money now

eventually you will get a reply telling you to order from xenocron( they would probably have it too) they have a lot of good basemaps if you want to pay.


you can always use stock gsr ecu and stock o2 so it runs in closed loop it will start up

 

That's exactly what I was going to recommend, them or Phearable. It's the easy button if you're not 100% confident in your ability to create a basemap yourself. It's also less than $40 iirc, so it's a pretty small investment in peace of mind if you ask me.

That being said, if your tuner is worth a **** he should be able to make a map that will get you broken in and to his shop. Have you asked him?

 

If you pull a few degrees of timing in the low load areas you're going to be in you will be fine.

I doubt you're going to be at W.OT. on the way to the tuner....

Also do a compression test. I wana know you're numbers. I have a stock b20 with gsr head and I'm getting 270psi across all four. I think that's like 11:1

 

Xenocron has a bin directory that has a few s300 calibrations saved. as always, use at your own risk

That thing is pretty high compression... over 12:1 for sure. Just be careful with it, it's going to be real picky about fuel.

Not sure why people keep building such high compression motors when gas is getting worse by the day.

 

stock bore gsr with 89mm crank and stock b16 pistons with slight headpirting and pro3 cams 218 whp
Just to show that no need for high compression

 

It definitely is, hence my hesitation with throwing any old map at it. I just don't want to get to the tuner to find out the thing won't even fire up for one reason or another so I'd at least like to know that it fires.

As for building for high compression, it wasn't my original intention, but I got a great deal on this after it was completely built with zero miles. Couldn't pass on the opportunity considering I was looking at a rebuild of my GSR block anyway that would have run me more than I paid for this without anywhere close to the numbers.

Plans are to get this tuned proper, all tags current, then see what I can get in cash/trade offers. If I don't sell, it's going to be a weekend cruiser.

 

You're better off with the JDM B16A basemap, adjust for displacement, add 5% overall fuel trim, add an extra 5% above 5,000 rpm for the IM. super basic, but that's exactly what I would start with.

 

i do like the timing maps better on the b16 files than the gsr ones.

thats pretty darn high cr for stock cams. its probably going to need a few extra degrees in timing retarded possibly up to 12" vacuum and somewhere around 2000 - 3500rpm.

additionally, keeping cruising afr closer to 14:1 than 15:1 might help, but there is no need to go stupid rich with it.

 

Start off from a B18 Type R basemap. Should get you close compared to B16s.
