I use the following Dashboard: "Portrait Numbers Only"


Not as flashy, but displays all I need and more. 😁

 

Have you tried just using the data grid option and adding PIDs to this?

 

while looking through here I keep seeing people speaking about the Sprint Booster. this looks like just a computer change rather than physical, would it be needed with a manic tune?

 

No it would not be needed.

Just to confirm the switch settings:

0 - nothing
1 - stock map
2 - Map A
3 - Map B
4 - Map C

With the cold weather I decided to try out Map B.

 

Yes, select what map you want on the dial, and then plug it into the port.
0=read, 1= stock, 2=A, 3=B and 4=C race map

Not everyone's map C is a race map. If you have any questions you should ask the dealer who loaded your tune since they would know your particular file set. We have customers with 100 octane Map B so every car/tune is different.

 

What's the consensus on the best meth kit these days?

 

I own the Aquamist HFS-3, most of it is plug and play, including the gauge. It's tailored for the Mini, and best of all, its boost and IDC controlled.

+1

 

Excellent thanks! That's pretty much what I've heard from everyone. Looks like it's getting added to the mod list.

 

My new better kit came today. Way better than my old kit.

Awesome!! That's a thing of beauty!

 

I figured out today that the car engine coolant is now set to ~180F (usually I had to be in sport mode for this).

Here's a log from stage 2+ map B. Very similar to map A. Anyone know what the installed flow limits are for a S stock turbocharger?

 

Depends on lot of variables having to do with air temp , altitude etc. Nick says the S turbo will drop down to 16-17 psi near redline in some situations. If datalogging in such a situation you will see "target" boost hit then slowly taper off. Lots of converting air density at given temps to figure out actual psi.

We had some fun with an R53 once. stock air to air intercooler made 15 psi @220F , GRS air to water made 12.9 psi which made us think it had a leak until we saw 145F intake temps. Turns out they are the exact same amount of air density just denser due to temp drop.

 

Your right, looking harder at the two data runs:

both in 4th gear @ ~5500 rpm:

Map A

Boost: 16.8 psi
IAT: 59 F
Advance: 8 degrees

Map B

Boost: 18.3 psi
IAT: 36 F
Advance: 6.5 degrees

The cooler temperature resulted in nearly 5 percent density increase. Boost was also up by 1.5 psi.

 

Wouldn't B be running higher boost than A anyway?

 

I thought map B produced more power than map A that's why boost is higher.

My understanding of what EruoTechsAZ is say with lower ita your required boost is lower because the cooler air is denser so you don't need as much?

 

What has me puzzled is that the mass air flow is the same between the two maps. Both are giving me 23.4 lb/min. The map A run was higher temperature and lower boost while the map B run was lower temperature and higher boost.

My first though is that map B should be giving me a higher MAF reading, and even more so given that the temperature is lower and boost is higher (much denser).

What am I missing? What is the output limit of the MAF (i.e at 5 volts?)

 

No our MAF sensors don't work on voltage like Fords and some other vehicles. It outputs a digital square wave that varies in frequency based on airflow. If you remember opening and adjusting the JB+ the chip your were looking at next to the potentiometer was a timing circuit that adjusted the frequency of the signal being sent based on input from the variable resistor.

No two pulls are the same even on a dyno. On the road its even harder to produce identical results. Changes in temperature, barometric pressure, road incline, weight of the fuel being carried, even tire pressure due to heating etc.. all play a role in load calculations the ECU is carrying out. Nice thing is the tune was compensating for the lower boost with more timing. So even if your turbo didn't come to play on that particular pull the tune did. Which MAF PID are you using?

 

Stage 1
Map A 23.1 lb/min
Map B 23.4 lb/min
Map C 23.4 lb/min
Graph is Map B

Just went to stage 1 last week and I like it.

 

Great, thanks for the explanation.

I'm using is sae.MAF

 

Now you need to install a meth kit. Especially when the summer time comes.

 

I know that I would like to install a kit. I'm thinking that I will wait until the Craven intake spacer with the port injection becomes available. That would seem to be a solution to valve carbonization as well, wouldn't it? Wonder how that is testing out by now?
