Street Build ITFLYS - 1Gina2G

[We're on Boost]

This e85 cap didn’t fit - the thread pattern is not compatible.

Ahh. Last year I had to buy a new gas cap for my BMW and I read a lot of bad reviews by customers on various odd brands of gas caps. So I bought a Stant and it is perfect. That's why I kind of took notice of your gas cap and asked about it. Should be a not very exciting topic but apparently it's not as simple as it should be these days.

If you didn’t know already the GoPro 4 has good heat characteristics, whereas the new waterproof versions trap heat and so they don’t work that great in some race cars.

Yeah I was reading about GoPro 11 and 12 last night and the overheating is an issue. But I also read that it's mostly the battery that gets hot, and you can solve that by using an external battery, like an Anker PowerCore 10k which only costs about $24. I suppose that wouldn't work for a camera on the outside of the car, but it should be good in the cabin. I haven't bought a GoPro yet and not sure I'm going to.

evo forum pointed me at this - a e85 gas cap from Stant - fits DSM

 

[Justin DuBois]

Fits

SMOG testing is complete - and yes, it passed on 100% e85. (I didn’t tell them, they didn’t ask, and the yelllow fuel cap wasn’t installed and the e85 sticker was covered).

I asked if there was any issue - and they said the hardest part was lifting the car enough to see the part number on the CAT

These old guys at the CHEVRON, know DSM - GST and GSX. One of the guys rebuild himself a Subie WRX STi. Mentioned how impressed he was with how smooth my engine was idling. Heh heh.

Love these guys.

Oh goody - this arrived! - Thank you to Cody Kenyon - (Facebook)

and… the under hood stickers I’m having printed are out of production and moved to shipping.

 

[Justin DuBois]

GoPro 9 did not pair with RC - bummer. ASL did offer to work with the camera to possibly engineer a solution - and I said Yes! Its not doing me any good in my hands so I’ll ship it to them for a while.

Where did you get the firewall tag? I have one myself but I know there are at least two makers of these so just curious.

Back on SD - Global Fuel adjust - Pulled out about 4% Global to put it back into calibration.

 

[Justin DuBois]

Thank you

I think the KN in box with stock cold fender intake is helping. The IAT’s seem lower overall. I’d need to push on it to really know how much better/worse this is. I’m still gonna open another 2.5” hole out the bottom of the box and see if spool is improved. The honeycombs have been removed, and I’m probably gonna go at the MAF with a saw and grinder to open it up.

Evo+DSM Timing tables. No No No knock knock. - E85 - Never gonna give- you- up!

Like @Stapl3 said, if you see knock on E85 you're probably already f***ed. You're never going to tune by knock on E. This is also the main reason I swear by and always run the Felpro composite head gaskets. They will usually fail instead of torching hard parts on an E85 tune that's too agressive. I turn my knock count as low as possible and have the CEL set to light off. You never wanna see that girl blinky.

That's impressive you passed CA smog. Surprised they did knock you on the visual for the aftermarket BOV. Was your downpipe and exhaust stock?

I've never been called out for the BOV - and No, I'm running RRE IC pipes. I PC'd them black. Maybe they don't attract attention? Also - the exhaust is not stock - 3", but the CAT is 2.5" with the correct "Cat" part number for this car. I think a lot of it comes down to the people. They either want to pass the car, or they don't. I also think the stock like theme under the hood goes a long way to counter anti-mod car culture. If it "looks" (and sounds) like it could have come from the factory - you get the benefit of the doubt. Very few people - mechanics included - really know what these things looked like when they were stock. I feel like I'm getting the benefits from herd immunity. Can you imagine the last time a mechanic has seen a t25 stock DSM? They just don't exist.

E85 has changed my plans. I'm going to look at much higher compression pistons and build the spare motor with more agressive specs.

 

[Justin DuBois]

Moving the floor - was 11, now 12. Once done playing at 12 - will target 12.5 for E85

 

[Justin DuBois]

These turned out pretty good

Where did you get these done? I was looking for someone to replicate the vin sticker on the driver door jambs...

I've been carting my original hood through two house moves for this day - I took pictures of my stickers, scaled and cleaned up the images in photoshop, and sent the files online to : https://www.carstickers.com

It's not wrong, but I'll never be enthusiastic over this. Running rich provides more insurance of fu*kery, adds cooling, and maybe adds a sliver of compression. It would be interesting to test 11:1, 12:1, 12.5:1 and see if there is an actual power difference.

As time goes on I keep going more toward running as rich as possible without blowing smoke, ignition issues, or out of fuel issues.

Yeah, that's fair. I think you're definitely right about the tech deciding whether they want to pass it or not. In the San Diego area they seem to be pretty strict. I never understood why they cared if the car was modded if it passed the sniffer.

I'm interested in what you did with the cat, though? What part number did you use? Talk me through that?

I've actually been reading a lot about (and researching) low compression builds lately. I think there's greater gains to be had with safer tuning margins on a low compression build with a super responsive turbo. I think a next level setup could be built around a moderately sized twin scroll snail, or even a VGT setup. The unfortunate part is you'd likely need to go standalone ECU to really make something like this work.

Just as a heads up. When i first started tuning with E85 back in 07 i also had my desired afr to 12.5. The problem with it being this lean is that you leave no window for error and things happen. I now shoot personally for 11.6-8 depending on the motor set up so you have a window to work with if things go south. I won't touch on timing since everyone has their opinion.

This CAT:

has the part number they were looking for.

Now I just need to get the color right on the yellow ones. I’ll borrow a Pantone color swatch book from work, and pick a number that visually matches the factory stickers.

Dropped my Boost low enough to cross over my VE Peak at 99 so that I can confirm the Global Fuel setting. Looks like I need to re-visit this map now that E85 and new targets are in place. Time to tweak my way back calibrated at any boost.

Curious about your methodology here? Why drop the boost level instead of calculating for your desired boost level and adjusting fuel to correlate to that?

Don't want to insult your intelligence since you clearly know what you're doing (and you probably know this), but you're aware the ECU is pulling data from multiple cells at one time, not just looking at a singular cell, right?
