Just using the factory one. I sent my datalogs to my tuner. Just waiting.....................................................

Can you throw throttle position up? Look how boost is fluctuating. Based on the sound you report, boost is circulating or reverting into a spinning compressor when it shouldn't. Or boost control could be messed up. Well depending on your throttle input I say this. But it looks like you are accelerating pretty steadily.

When you say throttle position, is that the same as accelerator pedal position %?

You can click on any of the logged parameters below to toggle them on/off.



Here's another log where I accelerate under similar circumstances, but no surging.

I spent about an hour driving around just doing similar pulls. Sometimes the surging happens, other times, it doesn't.

It would be pretty interesting to see ETC actual or whatever the parameter for opening of the throttle body is called.

Apologies if this has been answered in the previous 116 pages. It looks like the S280 kit comes with elbows plumbed for a remote BPV adaptor. Has anyone used plain elbows and an external BOV, eliminating the BPV adaptor?

What were the results? Is this still acting up?

Would there be any correlation to poor octane fuel and increasing coolant temps?

I know the stock radiator isn't great and it's a must upgrade. But with that out of the way, this past weekend I went on a road trip. I'm tuned on 93 so I started the trip with 93 in the tank and drove for about 3 hours, with some hard spirited driving along the way. My temps were absolutely fine at this point (and tbh, I never had issues with my temps).

Out in the "wild", gas stations only have 91, so when it was time for me to take my gas break, I filled up 91 and also hung around for 20 mins. I figured 91 would be fine as long as I don't do any WOT pulls and 20 mins is a nice amount of time to let the car cool down. But within a few minutes, my car started surging whenever I even tried to spool up, my OAR readings were dropping down to -0.70, and then my coolant temps went up to 245ºF, and for the first time ever, saw the coolant temp light go off.

Maybe it was just a coincidence.

An upgraded radiator will probably be my next upgrade... but FWIW, I don't live in a hot climate so this is literally the first time my coolant levels went so high in 7 years of ownership. This is also my first time putting 91 in after getting a 93 tune with the S280, so I was just trying to figure out if there's any correlation with the fuel grade and temps or just a coincidence of two separate issues happening at the same time.

That’s really weird man. I’m on stock radiator, whoosh intercooler and my thermometer is often above 110*. My coolant temps only approach 210 when I’ve been sitting in traffic.

I still do WOT pulls, just not as often or as long. Did a 800 mile trip to South Texas and didn’t have any concern about overheating.

A radiator upgrade might help, but if it’s been fine until now, something sounds like it needs maintenance.

Well I drove to the bay area and back on monday and tuesday. That’s 375 miles both ways including a sea level to 4k climb. This was in 100-110 degree temps highest temps I saw with a Mountune rad during the climb as 210 F . Once I hit the top it dropped back into the 190’s. Oh and the temps were still the same gotta admit with a bunch of semi’s around you will your climbing a hill it does not exactly means your pulling any real cool air through your rad either way:ROFLMAO:

Oh and I did LA to Palo Alto/Menlo Park on 3/4 of a tank up at an average of 80 mph and then did Richmond Ca to LA on a tank with 10 miles to spare on the way back at an average speed of 90.
Yes I had my wing slots taped off to reduce drag and increase mileage and yes that does work!

I had my first battle with the small rad. I was waiting for my brother to come out of the store with the ac cranked up. He was in there for 10-15 mins. The weather was super humid and like 97. When I took off, I gave her the beans and could tell she had cut power. Looked down and the gauge was all the way to the top. The temp light didn't come on or any other warnings. I turned off the ac and slow down to a nice cruise. It immediately started dropping back down to normal. I didn't have any boiling also.
I purchased the ebay triple core for it. But ended up using it on my stock fiesta. Guess I'll snag another and see how much it helps. I'm also thinking about wiring up a fan in front of the condenser. Ideally, I'd like to have it come on at certain temps but idk if that's possible. So maybe a toggle switch. It could be beneficial in stop and go traffic or pushing the limits of the car.

So, with my S280, I bought this BOV:

https://whoosh-motorsports.myshopif...280-free-shipping?_pos=3&_sid=41a8870ec&_ss=r

When purchased, my expectation was that a plumb-back was fine, as I didn't care about getting the loud blow off noise from a VTA valve. But, I have since changed my mind.

So, I just vented the exhaust port of this BOV to atmosphere and used a plug in the S280 hose where the BOV was previously connected. Definitely get the loud "whoosh" this way. Any downsides venting a plumb-back to atmosphere like that?

Why? did you not like the fact that you only here a slight whoosh with the plumb back? I run a Turbo Technics EV plumb back because it wires into the ecu like the stock bpv making the actuation faster. Never had a problem with. It’s quite though. I guess if you want the noise? Really the difference is your venting fumes to air.

Honestly, I just vented it to atmosphere on a whim to see the difference and decided I liked the noise. Obviously, I can put it back pretty easily. Especially if I’m told it might cause any issues…

Is there any issues with adding too much ethanol like E20 when just tuned with 93?
I still have lower octane fuel in my tank (from my road trip) and was thinking of just putting ethanol in, but I'm not sure how much I really need. But I figured if it's okay to put an "excessive" amount, then I'll just put in like 2 gallons and call it a day.

Even on road trips I use premium lower octane fuel is just a no go with a s280 in my opinion especially when your tuned for 93.

You're trying to counter low octane fuel still in the tank with ethanol?

If you're just trying to purge your system I would just run the tank low, then fill up maybe 2-3 gallons of 93, run it low again, then fill back up with all 93.

lol, 93 isn't available anymore once I venture out into the boonies, unfortunately.
As mentioned in my earlier post, even 91 isn't good enough for my finalized tune.

That's the best way, but I don't daily my car so this is going to take forever, lol. I was just wondering if I could expediate this without going for a drive to no where just for the sake of running down my fuel. It's also kind of a waste of money. This car is too fuel efficient.

Not trying to be a jerk, lol... but I was really just looking for a yes or no response to this:
"Is there any issues with adding too much ethanol like E20 when just tuned with 93?"

I'm not an expert on the fuel system so I don't know if this is fine or will it cause issues.

The short answer is that, with the 93 tune, you are tuned to 10% ethanol. When you go to 20%, the car will run a little lean. Is it enough to cause damage? Who knows. If it’s only temporary, you’d be okay to do it and just keep to lower RPMs (where being lean is less consequential) until it’s burnt out.

In theory, the lean condition is mitigated by the ethanol’s lower combustion temps. But no one will be able to tell you for sure the effects on your tune on your car under your driving conditions.

I drove on e50 once when I couldn't get 93 after adding a gallon of e85. I was just really gentle with the accelerator pedal. I would recommend against that though lol
