I wasn't even able to get up into 4th gear as far as I wanted on the road and was feeling the heat, so I def need to get that 300-cell DP on soon.

Any feedback is appreciated!
With so much logging you're doing I would get a Dragy (GPS Performance Meter)

I hear ya. Just trying to find a stable setup & tune before worrying about numbers.

The IATs look way too high in the 5.7 logs, and itís not even a 2H map. I donít think thatís a symptom of 5.7, just that I need to change the DP and then decide if I need to change the IC, as well.

DP will help a little bit ignition timing under high IAT, but doesn't change the high IAT.

Let's face reality. The intercool is no good. It doesn't even prevent IAT from climbing on your first pull. Good intercooler would decrease the IAT at first few runs.

In repeated 3-4 gear runs, the IAT is stable at 60F over ambient temp, either with your custom map (40F ambient) or OTS V5.7 (70F ambient). Unacceptable for the map you're using.

Agreed. Makes sense with the heat issues I was having even with Dinanís tune.

I want to do this a part at a time to see the differences in the logs, so Iíll go Wagner Evo Comp II first, log, then DP, then log.

Alright, I've got an update for you guys.

First, I changed the Dinan IC to a Wagner Evo 2 Comp. When driving at higher speeds, in medium traffic, or stop & go it's keeping the delta b/n ambient and IAT 10-25F lower than the Dinan, so that's good. I also added the do88 larger remote radiator to go with my CSF radiator, oil cooler, and DCT cooler.

As for the outcome, I have mixed feelings. You'll see that I gave the car a workout to try to emulate hot summer track days. The Wagner is definitely helping, but higher than 93 octane will be a must. Even with that, I'm not sure how much more I could really push on track with the Stage 2 93 5.7 map.

Stage 2 93 5.7 with Wagner - Ambient 78F
I had already completed a few pulls before I remembered to start logging, so temps are already up in this log. IATs were at 94F before starting the initial pulls.
http://www.bootmod3.net/log?id=5cb90b36ae729b44f4273e3b

Stage 2 93 5.7 with Dinan - Ambient 70F
http://www.bootmod3.net/log?id=5c8c421dae729b3511ea8fd1

Stage 2H 93 5.5 with Dinan - Ambient 40F
http://www.bootmod3.net/log?id=5c2c9014ae729b51747a4b72

As for general drivability, 5.7 is smoother around town and has more power in the low/mid-range. Altho, my Stage 2H 5.5 map feels stronger up top. And, the last possible upgrade item would the switching the stock DP out. Not sure how much that would improve what we're seeing here.

Any feedback is appreciated!

Im not qualified to critique your logs, but I can offer-up for comparison a log I captured during some open lapping this past weekend. My car has Evo2 comp IC, and the BM3 Stg 2 93 V5.7 tune, so there are some simularities. Big differences are my car has a 300 cell DP, stock turbo, and all stock coolers. Ambients were at 73 F. Shell V-Power 93. DCT auto upshifting at 6800 to 6900 rpm typically.
My untrained eye doesn't spot any red-flags on my logs. Car ran great for more than 7 hours total of hot lapping over 2 days. I’m impressed how the coolant, engine oil (Motul 5w40), and IATs hold-up despite the abuse. I am tho apprehensive of how temps will hold up as ambients climb this summer. When that happens, I’ll likely try the Stg 2 91 OTS tune and take some more logs.

Thanks for posting this! Iíll dig in in the morning.

Iím assuming Iím generating more heat bc of more power from the Dinan turbo, but Iím not sure thatís how the tune adjusts/works. It would be great if all I need to do is change the DP!

On the only real WOT part of this log you have 4 knock events in a single 4th gear pull. Youíll either need more octane to run this map or drop down to the 91 ots.

The American fuel quality for its advertised octane is lower than other parts of the world, that is obvious from the multiple logs we have seen. Iíve personally ran the race fuel map with much cleaner logs on my pump 99 ron which should translate to 93/94 octane.

Yeah, I was also using Shell V-Power 93 and it just doesn’t seem like it’s enough. Anytime I add a little race gas it really smooths out the power delivery. I’ll try adding a little Boostane to see what that does.

Other than that, M2MGM your logs look pretty good to my inexperienced eye. It looks like I’m definitely taxing the car more with the back to back full 3-4 gear pulls. Heck, I almost had my front tires up to track temp with no lateral loads (was at 155F), just from all the heat under load, low airflow from the decels and my APs getting warm!

http://www.bootmod3.net/log?id=5cb90b36ae729b44f4273e3b

Halim isn’t satisfied with what he’s seeing, so we’re going to try a couple things to figure out if changing octane, the stock DP, or map tweaking helps.

I did notice the knock, but wasn’t sure if they were spurious / harmless events, or something more important. I’ve noticed them also on other peoples OTS Stg 2 93 5.7 logs that have been posted so, I’m beginning to believe the V5.7 tune may be a bit too aggressive....at least for my local V-Power. I’ll try the OTS Stg 2 91 and run some more logs. I’m completely open to trading a few ponies for a safer tune.
Thanks for your comments.

Cool. Hopefully your /Halim tweeting can result in a solid tune for other Dinan turbo users...although youíll probably need to swap out your stock DP for 200 or 300 cell for an OTS tune.

Think Iíll add some octane booster to my tank and will redo the logs to see how that impacts things. Will post up when I have them.

Here’s a Stg 2 93 5.7 log with octane booster. Octane should be equivalent to US 98: http://www.bootmod3.net/log?id=5cbe507cae729b40cb5a8b25

I didn’t get to push as hard with the 98 octane pulls, but the car felt better than when I logged 5.7 with 93 octane: http://www.bootmod3.net/log?id=5cb90b36ae729b44f4273e3b

That said, it still isn't as smooth up top as my Stg 2H 93 5.5 map on 93 octane: http://www.bootmod3.net/log?id=5c2c9014ae729b51747a4b72

At this point everyone will say it’s the stock DP that’s holding the car back, but I’m curious how the logs agree/disagree?

Thanks guys.

Alright, here are some E25 runs on the E30 map: http://www.bootmod3.net/log?id=5cec6f8ac090c61270ad0b22

The logging messed up a bit and I had completed 3 pulls before these and went on for about 5 more, driving the IATs all the way up to 135F, even with the Wagner Evo 2 Comp...

I started at E25 just to make sure I wouldn't have any issues with the HPFP. HPFP looks good, along with timing and everything else. No earth shattering changes on the power side (feels like 5-10hp more?), but I will say the car felt smoother thru the rev range and a lot better on the top end, especially as IATs rose.

With the Stg 2 93 map and 93 octane, you can feel the timing start to crack up after just a few pulls. Octane booster helps, but you still feel it as IATs get above 125F.

With the E25 on the E30 map, no feeling of timing pull even when I drove IATs >130F. There was reduced power, but it wasn't rough feeling like Stg 2 93.

Overall, the car feels good and I'll bump the fuel up to E30 next time. And, I should finally get my DP installed next month!

If you could get the IAT under control your E30 log would be good, you were getting knock on later pulls due to heat. You must be roasting the stock cat, you should feel a huge difference once its changed.

Changing from the stock DP is all I have left to complete my FBO + Dinan turbo build. I donít expect changing the DP will impact IAT much, so short of changing to a huge lag inducing FMIC, WMI, or detuning Iím not sure thereís anything more I can do about IATs.

Please do start a thread up on this. I'm speccing out a WMI system myself at the moment and would be interested in sharing notes / plans etc.

Yeah cat won't affect IAT, meant you will feel the extra 20-30hp when its changed.
