You're only hitting 19.2 PSI?

Woah, also 20 degree delta on coolant temp during just the 1 pull.

Sounds about right with the boost with the weather here.

I had not looked at the coolant temps, but that also doesn't surprise me with the weather and the duration of this run. Take your car out to BFE, bog it to 1400rpms in 4th geat and wot it and see how long it takes to get to 7,000rpms. Felt like it took 3 miles to get to 125mph, lol.

You mean 2700lbs?

Do you have Accesstuner? *LOTS* of room to go your current tune.

Good lord you need a FMIC upgrade.

+40F charge temp gain over a 4th gear pull!??!?!?

I'm pretty sure he's using OTS Cobb Stage 3. I'm going to try to pull a data log today, but this morning it was 50 degrees, and I was peaking at 22.8psi with Cobb Stage 2 OTS, and in 4th gear it holds 21+ psi from 2,000 to 5,000 RPM (until I lifted). This is my first turbo car, and i'm fully amazed how much of a difference ambient temperature makes.

 

[ryst]

Alright, here's some logs:
http://www.datazap.me/u/ryst/815-pulls?log=0&data=8

12 and 13 are partial 4th gear pulls and log 14 is a full 3rd gear pull from 2300 rpm to 6500 rpm

Cobb Stage 2 OTS
93 octane
Ambient temp around 75 degrees, low humidity
No other mods

 

[ryst]

Some more boring logs from a stock FiST Same parameters as above, but 64 degree ambient temp (for log 16-19)

I'm still not willing to go out to the red line in 4th, so anything that revs less than 6000 rpm is a 4th gear pull.

sourskittle,

See, this is exactly what I was talking about. Check out your 4th gear log here, see your STFT go +20 right where your HPFP pressure dips?

http://www.datazap.me/u/sourskittle...full-4th-gear-pulls?log=0&data=8-9-18&solo=18

If you had the proper tune for E40 your STFT wouldn't have to make such a huge drastic change to maintain target AFR and your HPFP wouldn't drop pressure

 

[sourskittle]

But after it sees the same thing, TIME AFTER TIME, shouldn't that become LtFT and it know that its coming?

I'm selling stuff around the house to buy access tuner btw, lol.

It's a small event, and a short amount of time in the grand scheme of things. Usually LTFT is time based. Meaning, STFT has to be +/- a certain amount, for a certain amount of time to be added to LTFT and reset.

Also, LTFT is for long term global adjustments, STFT is for very quick short term adjustments, like what we are talking about.

 

[sourskittle]

Tin foe. I promise.... If I had access tuner, I'd load your tune and have datalogs tonight, lol.

Testing out my new custom intake before the addition of a heat shield.

You should log intake air temp, I believe that's pulls the temp reading from the MAF, which would likely be the best indicator of how well the heat shield works.

 

[ISO100]

Yep. I plan to add that to the list of variables I log after I get it installed.

After driving it a while I definitely feel more power at the higher RPM range even without a heat shield. It's a noticeable improvement.

If it doesn't rain all damned weekend I'll be able to get some progress on the heat shield.

Actually AIT is measured by the Boost/temp sensor in the tube between the IC and throttle body. The PID for outside temp is measure by a sensor located in the plastic radiator cowling behind the grill, RH side near the OEM air intake. Can't really see this sensor until you remove the bumper.

That's the MAP sensor. Charge Temp is measured around there, post turbo/intercooler, Intake Temp is measured pre turbo/intercooler. Ambient outside temp is measured by the sensor you stated, behind the grill.

Strange as it may seem and I had to check this with a heat gun but AIT which is shown as IAT on my OBDII scan tool is measured at the post intercooler pipe by the sensor I mentioned above, so its really charge temp. Out Temp from behind the grill which is different to the dash reading.
I remove the MAF, stuck it in a length of pvc pipe and used the heat gun on this too. IAT temp didn't move, that's when I went looking further.

I think we are saying the same thing.

OK, I understand you now. Technically a MAP sensor (manifold absolute pressure) is fitted to the intake manifold and this engine has a sensor in the intake manifold, don't know what Ford calls it because they call the sensor in the IC pipe a MAP sensor?.

The sensor on the intake manifold could be another MAP sensor post throttle. To be honest I haven't taken the time to track down all the sensor locations yet. What I do know is that the sensor in the IC pipe pre throttle and post intercooler is a MAP sensor and the sensor pre turbo and post filter is the MAF sensor. Usually the pre intercooler IAT sensor is part of the MAF sensor as well.
