Ok, I misinterpreted your post. That's on me.

To clarify what I was talking about with regard to heatsoaking...In my experience, and this goes back to the GTO community I was a part of from 04-08, when car kids argue about heatsoaking on intakes it tends to refer to increasing IATs as a result of the box itself getting hot - i.e. a metal box transfers more heat into the air and thus will be hotter. Which is nonsense, as experience with tuning and monitoring bear out. Yes, IATs will definitely be high in traffic. With any intake, including stock, no matter what it's made out of or how well it's insulated. But as soon as you're moving, it'll drop back down to very close to ambient. Again, that's with any intake.

And yeah, WRT your tune, I have noticed that from the OTS Grimmspeed Stage 1 tune I could stand to do a little work on the tune as my LTFTs never get down below about 3-5% but it's been so bloody cold lately I haven't messed with it. I'm not going to tune for the 60 days a year of solid below zero temps, know what I mean? That said, IAM is always at 1.00 and I never have any knock, but it could definitely be a little better as the LTFTs show.

Definitely- if there's no knock (a little FLKC doesn't hurt things) and IAM stays pegged, you're probably alright. It seems strange Shiv spoke so nicely about the intake but the OTS tune is so far off it's weird.. has me thinking something else is going on over there

I am in the same boat as you- I am worried that it's a shit time of year to do tuning; Washington has a ton of variance in weather so I'm thinking of creating two tunes, one for summer, one for rest of the year.

When things clear up, hit me up and I'll lend any support I can. I use @vgi's Java plugin and Steve as my advisor for when I don't understand something, haha.

I am also playing around with zeroing out the IAT comp table and tuning from there, but I don't understand that approach yet so I'll let you know if I make any breakthrus on that front

They tuned at some shop in Southern California at say 1,000' altitude on a 70+F degree day and I'm sitting here at sea level at below 30F. It does make a difference. More air so there's more fuel needed to get to the commanded AFR (which it's always easily in reach of).

Bumping this, has anyone used the AFe Takada intake with an oil cooler?

What about the Skunk2 airbox?

What about the Skunk2 airbox? It clears the Skunk2 oil cooler lines. Though I don't have an oil cooler yet, here's a picture of it installed. I'm using it without the restrictor, so it's a little over 3" wide through the MAF adapter, and it has air straighteners inside to restrict turbulence. It's made of heat resistant plastic material to resist heat-soak better than metal intakes. It makes enough power with my long-tube header to squeal the tires from a standing stop in an automatic, and that's more than my stock intake could do. It also has a rubber ring where the tube passes through, which ingeniously absorbs the engines' torque thrust against the body-mounted airbox. Other setups can work their way loose while this won't.

FYI, Grimmspeed is working on a solution for the airbox to work with oil cooler lines, and plan on letting the initial crowd of buyers looking to use an oil cooler swap out with the revised box when it's ready.

There's no ETA on this yet though. Grimmspeed takes good care of their customers.

GS, don't look back. Wait for the update re: oil coolers if its that much to you, shouldn't be to long.

Grimmspeed Intake all the way.

Exactly, any canned maf scaling from any vendor will never be as good as doing it yourself
altitude
temperature
fuel formulation
fuel ethanol content ie 0 to 10 or so % in petrol

and variations in the actual maf sensor itself due manufacturing tollerance or revisions, their apears to be at least 2 variations. mine always ran rich and i see it in other guys logs as well, some run rearly good and some like mine run about 7 to 10% rich on stock intake. even on stock tune and intake.

Yes, not being able to have an oil cooler is a deal breaker.

I want to get back out on track since I parted my Miata last year.

The Perrin is pretty solid if you don't mind fiddling with the front bumper. Can be done without removing it but it's a little trickier.

They're updating to allow oil coolers, so soon.

While you likely want to fine tune, MAF scaling doesn't seem the mess it is with so many, and that's a safety issue too. Is the basis of my recommendation, at any rate.

^Yeah, I'm just curious how long that will take. I suspect it will be months down the road.

I wouldn't mind pulling the bumper to install it, since I'll have to pull the bumper to install the oil cooler.

But having to regularly pull it to clean the filter, that's not so appealing.

Yes, I know they don't make any power once tuned compared to stock. However, I want to clean up the engine bay.

Requirements:

1. Doesn't interfere with oil cooler lines (I'll be using the Jackson Racing setup).
2. Don't have to remove the bumper once per year to clean the filter.

Thoughts?

just the JRSC oil cooler or SC/oil cooler combo? The SC will replace the intake if this is the case

Just NA. No desire to drop $7k on FI......even if I had that laying around!
