Do you have both your fans kicking on at the same time? Not sure how you've got them setup but presumably you could stagger them to make the shock less significant when they kick on.

I have one set to turn on as a cooling fan, the ac fan is another spal, but set to turn on with ac and/or temps getting too hot for the cooling fan to manage, there isnt a set number ive left the cooling fan at rn, mostly to find a nice spot where I can avoid having the fan cycle constantly. Its just the one turning on thats killing it. They arent even huge fans, just 2 spal 30101522's. Factory wiring.

Trying to find my particular boards wiring to setup a programmable output to use the idle up feature. Would you happen to know how the logistics of that would go? These things always confuse me for some reason. Im thinking a programmable output to turn on the idle up feature at the same coolant temperature as the fans, so that it basically does them both at the same time, that might work, but im not sure it would go as perfect in use. There is an option to use Fan duty in the programmable outputs, but not fan on or off. Im going to check and see if it even knows when the fan is on.

If your fans are on/off then I'd assume that duty cycle 0 would be fan off and any other values would work for the fan on. I think you could set the fan output to a virtual and then setup some programmable outputs to idle up, delay for a tiny bit, and then kick the fan on. It would probably require 2 or 3 programmable outputs, but I'd assume you could do it.

I had to add wiring to my old board for the AC Idle up, but that was just because the ECU had no idea if AC was on or not. With the ECU controlling the fans I don't think you should have to do any wiring.

Are you running those on the stock wiring or did you add relays?

Id expect the same thing, but testing just now revealed the fan duty cycle stays at 0 regardless on or off so that rules that out

My speedy looks at pin 37 which is the stock ac request input, and uses it as a trigger for the idle up, but you can only use one pin to trigger it. For now, I havent even refilled my ac system since putting the engine back in, and its pretty cold here rn anyway. So I think I'll change the trigger pin to the stock fan, and thatll work.

What im thinking would work, is just adding a resistor between the ac request pin 37 and the cooling fan output. So when the cooling fan is on, or the ac request is triggered, it will idle up regardless. Im not sure if this would cause issues for anything else, but logistically it makes sense with a resistor i think...

I still think you should be able to accomplish that without any wiring. If you could pipe the main fan and AC fan to virtual outputs and then OR those together to trigger the idle up I think you'd have it idle up when either fan kicked on. Again, I can't remember how the speeduino firmware handles virtual inputs/outputs though.

step one would be figuring out the pins for each thing i suppose, ill look more into it and report back

I have nothing substantive to add other than a hello from an ex-Lubbock resident. (Tech alum)

Nothing new to add. I ordered a dual 10AN catch can and lines, plus the fittings to tap it. Ill do that next thursday. Im really hoping there isnt an underlying issue that is causing this. I went out last night for a small bit of shenanigans, and it filled the can within not very much driving, and not any boost.

we finally got some snow, and a snowstorm coming here. Last time i remember a good snow storm here in lubbock was like 2016, where my sister hit me in the head with a shovel. Anyway. Here i am ecstatic to take my stickyish summer tire, aggressive clutch, rwd, higher horsepower vehicle out in it.


again, nothing new, waiting on the catch can and swinging the car around in the one snow we’ve had

Jealous that you can take your miot out in the snow a few times and not instantly turn it into mush since you guys have no road salt.

Yeah its a special time when we get snow, everyone forgets how to drive, no salt, panic buying toilet paper and water. Im just happy to swing my car and not ruin my tires. not having to worry about the salt is pretty nice though.

FINALLY my 10AN can and lines showed up after a week, amazon said it would be 2 days, but a lovely snowstorm vetoed that i suppose. Anyways i got that installed. Lately ive been finding myself just wanting to be done and over with when installing things. I dont want to take the time to do it pretty or make/paint mounts for things or clean things up well, or care if it looks good, just want it to work. Im guessing im just hoping the car works long enough for me to actually value anything other than it working, plus i hate the cold, which it has been in the garage. I did end up making a mount for the can, and tried to make the lines not look horrible.

Everytime i take a photo of the bay it just seems like there is a lot going on. Which is funny because ive done a lot of consolidating of wiring and other useless items. Id like to have an uncut valve cover and timing covers again, definitely grew out of that a while back. Plus the mess at the back of the head doesnt help.

I did degrease and clean the bay after this, it was covered in coolant splash, oil film, and actual oil goop that came out of the catch cans and overflow over time.

I am however super pleased to announce what i think is another win, drove all day with the car after changing the oil, did some pulls, though not many because its hard to get the tires warm enough to think of hooking up- checked the can tonight, a few drops of water is all it could muster.

i was filling up the breather side within 5 or 10 miles there at the end when it was cold and snowy. And my pcv side can which was also vta -
https://cimg9.ibsrv.net/gimg/www.mia...c25001f55.jpeg
was about half full of water and other goodies. Glad i was catching it all, not glad at the rate. Pumped that it seems to be fixed. I went ahead and re rtved the baffles on ofc, took extra care this time. No scrubbers, but extra holes between middle and breather side baffles. i love the look of the AN lines.

boy does this motor breathe. Ambients were about 50f today, and i could see the air coming out of the filter at idle, and at night with the headlights on, it looks like my bay is smoking. I doubt this will be a long term thing, just a combination of temps humidity and e85 maybe, but still odd to see.

Not much new, passed 670ish miles on the engine which is where it gave up last time. Got a video of it breathing. The breather air smells very acidic, and fuel like. Im hoping its just the cold weather making it have so much vapor, ive emptied it twice with not much coming out, and what comes out is acidic smelling water, clear, but not fuel or coolant. Just the nature of the beast. The only thing bothering me with the car atm is the tune. Namely the uncertainty of it stalling randomly.
ive been wanting to try and dive more into fine tuning the car. It drives id say 95% well.

I feel as though the intricacies of getting a car dialed in are not easily or often told in enough detail to satisfy my curiosity. Id assume mostly because those who are good at it do it for a living, and dont want their lively hood jeapoardized. Tuning ae for example, mapdot or tpsdot? What baseline numbers? You just try things until things work. How do you know theyre working as best as they can be? I had more examples of these things but I have lost them atm. Still need traction.

Out of curiosity, what tires and size are you running?

Regarding tuning, I still play with my tune all the time. Usually because there's some little drivability quirk that I get tired of and realize I can tune out. I used to jump on tunes.speeduino.com and look at some tunes on there, but it's a bit of a crap shoot on if the tune is good or not. I've found some tunes on here from people who had a dyno tune, which is better. IMO finding a tune review thread on here where someone (lets be honesty, it's Curly) give good feedback and/or tweaks someone's tune is usually the most useful to me. You could also just ask for a review of your tune and a log of specific issues.

Specifically regarding AE, I'd start with whatever is in the basemap and see how the car reacts when you stab the throttle. If it bucks then note where the MAP/TPS DOT is and add some fuel. If it doesn't buck then either leave it or pull fuel until it does start bucking and add some back in. I think you can get away with pretty rough AE settings without too much of a downside, as long as you're getting enough fuel in there. IE, too little AE is going to be way more of an issue that too much. Having said that, if you're adding way too much then the car will stumble as well, but in my experience it's usually too little fuel.

215 Falken rt615k IIRC, not huge tires at all, but at least somewhat "sticky" They gripped up nice in summer, but that was likely 190hp and hot tires. I definitely need wider rears (wheels and tires) and wouldnt mind getting some nice overfenders to also cut out the rust in those panels, would be like 2 birds with one stone. I suspect my 4.3 diff has something to do with me being unable to use much power in my lower gears. I randomly passed my friend in his SHO and tried getting away, downshifted to 3rd and he said he saw me going sideways. I want a SHO...

I also dont leave in my car without my laptop unless its a quick errand. I also like watching coolant temps. I really need to get a day and just mess with it for hours trying to fix a bunch of the little issues I find. I like looking on the speedunio tunes site, but a lot/most of those tunes use OL idle, and arent otherwise different from my tune in a lot of areas, though I do try random things I see to see what difference it makes. Ill sometimes email Chris with speedy, but thats only if im really at a loss, like I am with the stalling. I emailed about the fan idle up stuff and he gave me some tips on using a richer idle and just dialing in the idle better for it to be stronger. That definitely helped, but its still not 100%

That little rant was really actually caused by just thinking about the little golden nuggets you find all around facebook and these forums (yes mostly curly) Where someone will drop the absolute method to getting something 100% dialed, or a perfect solution in a tune for something, but itll be hidden in a forum or facebook comment that you cant exactly search up. I usually screenshot them when I see them, because theyre great to have. In the end I suppose its just trial and error.

A bluetooth dongle and MSDroid were awesome when I was running speeduino. Since it's Arduino based you just need a generic HC-05 (HC-06 maybe?) dongle for like $10. It's a bit finnicky to get working, but you can use that like a digital dash and even change your tune from your phone. It actually gave me more control over the ECU than the current CAN/OBD2 setup I have with the Torque app.

Again, it's far from a perfect setup and I struggled to get it working, but once I did it always gave me some peace of mind.

I have a bluetooth module on the speedy already to fix a connection issue with my laptop through the serial cable, im guessing its the same one? That would be great, but i dont have a spare android device to run msdroid on, ill look for one on marketplace.

Yeah, should be the same Bluetooth chip. I've been on android forever so I forgot about the Apple compatibility. Not sure if there's a way to get that working, but a cheap android phone should work fine.

Yippeee still trying to get idle 100% - i dont think its going to happen, I went open loop for a day or two and tried tons of stuff there, it works when it wants, and not other times. I cant seem to find a rhyme or reason for it. Anyway, Im thinking of getting the speedunio to epicefi adapter board from dcwerx. Looking at the Epictuner, and pros of the stm32 h7 board over the arduino, and talking to some of the people who have used it on discord, it seems like itll get me the idle features and tunability im craving. Just poking around the epictuner, I love how the gui looks from an aesthetics standpoint. I know tuning interfaces arent necessarily meant to the be aesthetically pleasing, but this one is. The features the board claims to add are pretty extensive, even just getting the idle features would be great.


I would love to just bite the bullet and go for a link or ms3, its not in the cards atm, and for 55$ and some waiting I can give this a go. Seems like a no brainer, at the end of the day, if it doesnt work well, I can easily swap the ardunio back in. Max waste is some time and $55 so I guess we'll see. https://cimg6.ibsrv.net/gimg/www.mia...2f7050d81e.png

On another note, I keep pushing LOTS of oil out of my intake camshaft seal, I replaced it with a spare I had lying around, and still tons of oil coming out. It wasnt super bad when I had first started driving the engine. Im not sure if its walking out or blowby is pushing by it, but im getting oil everywhere. Going to get an oem seal and try that. I have more spare seals, but theyll do the same thing in the end.

Oem cam seal ordered

in the meantime, i was working today and realized ive never done a fourth gear pull. Tried one and hit boost cut at 235kpa, turbo made a funny noise- didnt flutter, then turbo stopped spooling up or whistling. Still spins good in its housing, some in and out play but nothing crazy, gonna check the wastegate flap tomorrow but I think a quick order of a china 2871 is on tomorrows (todays?) calendar. Need something to get on the road and dont want to spend 600$ on a pulsar for a motor im not certain will last very long. Will update if i hopefully find a smoking gun!
