General Supercharger Thread

This was at idle. I can pull up what the MAF was doing on the same screen (that was my next stupid question what values should I be seeing from the MAF). The lower of the two LTFTs just go more negative. I dare not drive it so lean in the 19s

 

You can spray some maf cleaner or similar for a rise in rpm's. I like maf cleaner as it dispute quickly.

 

Yes I saw this test with butane. I'll try this tomorrow. It is running so rough I doubt I will be able to tell.

 

Considering both banks are running lean, that would tend to indicate it's not an exhaust issue, unless whoever was fucking with the exhaust messed up both sides the same way (possible but seems improbable). As others said, it sounds like an air leak near the blower. Has anyone screwed with that? Emissions people maybe yanking on hoses or something? Since both banks are acting the same way it also implies it's not bank specific, ie it has to be between the blower body and the MAF. PCV, port for the fuel pressure regulator, throttle body?

 

This! Although my issue was my fault it was a rolled o-ring on the snout. Super lean and ran like crap.
Another time was when I tried to tune combining a heavier airload and increased throttle angle. It ran super lean. It sucks but aside from spraying cleaner or butane. A disassemble from airbox to TB and a solid look over with reassemble?

 

Picking up another truck on Sunday to install a blower on. Dude is keeping it stock, but we decided to do a catch can. So I'll be installing the $32.91 Amazon one on this truck

Also I checked Radium's website, and this catch can is actually quite a bit bigger at 300ml vs the 200ml Radium hahaha, so I'm not sure if there's any point to get a Radium. And there's even an "upgrade" for this that includes two inline check valves you can get, and that bumps the price to $40 Anyway, I'll get some photos next week of how I mount it in a Tundra after talking about it for other vehicles. I guess the Radium you get a bracket, but for $5 I'll mail anyone a flat pattern bracket to save you $200+

 

So O2s are reading super lean and ECU wants to go leaner (negative number). O2 is reading correctly and consistently across all three (when the narrow bands aren't pegged out at ~18). ECU should be going the other way. This eliminates O2s as the problem, correct? Still trying to find my wideband bung to look for a leak, found the other two.

Will smoke both sides, intake and exhaust, to test for a leak.

 

I wasn't sure if your hyphen was actually a negative sign, but since you confirmed that that is even weirder. I assume you've unplugged the battery to reset it? If you do do the fuel trims reset? I had a guy, I think @Abell207 maybe? Where the fuel trims were stuck in one direction after a tune tweak, it was really weird. So we adjusted the tune so itd run kind of close to normal at full fuel trim and then it could try to work itself out, which it did and then we would adjust the tune another 10% and slowly get the fuel trims to work back to zero. It was really weird, but was similar to what you're describing.

 

I got a 70.00 smoke machine from Amazon, it once & for all showed me where my vacuum leaks were on the BMW.

Also was looking for a CC. Ordered the PS and they let me know they now have a redesigned CC. Was told they're being made right now and it'll ship out a week/week and a half. I haven't seen they redesigned version so not sure what was updated.

 

With the SPD I have had to revised the MAF table a few times for I was creeping lean at partial jabs and especially WOT. After about 3 revisions back to 10.5-11 range but could still use a little more fuel up high.

 

Yes frustratingly weird. It does seem like it didn't reset after unplugging the battery.

 

Does it still vent to atmosphere? Sometimes in wet climates it can cause condensation to form inside valve covers.

 

Honestly I am not sure. Was just told old ones are done and new ones are being made.

 

This thing is tiny.

 

Where’s the link lol

At least it's redesigned so you didn't end up buying the worst one made, unless they one up themselves with the redesign

 

Sorry to derail the thread:

Can I ask what OBDII connector to laptop is recommended for data logging?

I'd like to get some of this perifial items in my cart for when I finally drop the coin.

 

I just use HP Tuners MPVI3 module. It is the same module you can use to flash a new tune to the truck. You need to purchase “credits” in order to write to a vehicle, but you only to purchase the hardware itself to read a vehicle and datalog.

The MPVI3 can be setup to datalog without a laptop connected to it, making it a little more convenient to go for a rip without all the gear in the front seat.

 

Great info, if course it segues into another question:

What is considered a " test" run once the logger is functioning?

Please don't tell me I have to run the truck to church.

I've never bounced any vehicle off the Rev. Limiter. I don't know if I'm capable to keep my " foot in it".

 

The HPTune thievery continues. 24 bucks to ship 12 ounces ground.

 

Well shit. My luck it'll be worse

 

This is the one I got

Maybe I'll upgrade my $260 Radium to this. lol

 

I have one similar without the breather as I live in a wet climate. The micro mesh filter works great.

 

You can leave the breather off. It has a plug

 

If your going to run the stock tune provided by the manufacturer than not much to worry about.
You can data log with varying terrain hills traffic with acceleration etc. To dial in MAF, timing and PE you'll need a heavy foot on the pedal but not bouncing off the limiter. The rest can be based on what the truck is doing on the data provided.

 

Probably the bare minimum for anything shipped UPS.

 

I had to send a 10 card and paperwork to New York, fit in a large envelope that would have taken a dozen of these 2 day for 16.99.

This is robbery.
