I did all of the above plus the M3 ABS/DSC unit and a 1M rom for the DME.

Do you have a post on these particular modifications you've done? I'm very interested to understand what all this would entail on my 335is build.

To whomever recommended swapping out the intercooler, thanks for the advice. Car came with a 5" and I'd figured it'd be fine for what I had planned and man was I wrong. The 5" was showing a 30-40F increase on a 3rd gear pull. I knew it wasn't the best based on the advice and it's performance, but when my tuner pushed me to swap it I knew it was time.

Anyway, went from 30-40F delta on a 3rd gear pull to a 0F on the same pull. I had no idea the VRSF 7.5" race intercooler would make that sort of difference. WOW! And I'm not a shill for them, but do seem to buy their products every once in a while.

Looking good 👍

Might want to upgrade the LPFP as its dipping into the 50's already.

[Grip Grip]

Ok, so the car is trapping 125 in the 1/4 on 93 octane and 97 in the 1/8th (Dragy verified), which seems decent for that fuel. What say you? As a result I loaded the E40 base file (datalog below) and will be working with Chris @ Motiv to get it dialed in. Hopefully he'll get that number up to 105 in the 1/8th and low 130's in the 1/4 with the ethanol. Not sure if that's realistic.

By the way, I've already purchased port injection, AIC1, and have the other half of the stage 3 LPFP setting in the garage waiting to be installed in case I need more. Not sure if I'll go all out and shoot for 700whp or be content with high 500's WHP on E40. Car is already spinning like crazy on the base e40 file and 16" MT ET Street drag radials on the street so will only get worse if I keep turning it up.

Regardless, I don't want to be buying DCT clutches anytime soon so I'll be installing the XHP tune this weekend. I'll likely leave torque limiting in place during shifts for peace of mind.

Anyway, just an update on what's going on. Suggestions are welcome.

Over all, the log looks pretty good. I think you might even be able to turn the boost up a little more. You do need to get the upgraded fuel pump in though.

Best I could do in the 1/4 was 11.6@123mph on PSS4S's.

Are you using the launch control at the track? I've only run this one once at the track with LC and it was a spin fest, but the DR's were at 25psi to keep from breaking an axle on my first time out. I got it into LC and once the RPM's hit 4,500 I'd let off and when they dropped to 2K I stomped the gas and let off the brake. Didn't like the idea of dropping it a 4,500. At least not yet. Is that how you're launching it?

For FF to work you need an Ethanol sensor in the fuel line.
And Motive has a FF analyzer that taps the ECU and adjust the maps for FlexF.

I would recommend getting a Differential brace too, it helped my car lock the rear end up a bit from swaying.

I test at the track a lot but don't expect great times. Getting a DCT to launch is super hard and your 60' is going to be terrible. Best I have done so far is 11.6 at 124 mph on Pilot SS4S's.

Solution, and controls your additional injectors. You'll need 750CC for those power levels.

Very nice option, especially if I didn't already own the AIC1. I can still go the flex fuel route though with the MHD module, but I'll look into it. I've got the PI and 750cc injectors covered.

Loaded a new Motiv E40 revision today which dropped the 60-90mph time by half a second, datalog below. The HPFP is dropping to 1050psi around 3,750 rpms but the LPFP never drops below 65psi. The HPFP was dropping into the 900's before this revision. I'd guess I would benefit from PI right now, what say you guys?

Those are seriously low HPFP readings,

Install the PI and LPFP 3, since you already have them, and relog,

Hopefully the HPFP isn't failing.

Shift looks crap there, your timing should only drop for 1 scan of the logging. That must feel like hitting a wall when shifting.

That was a base file that needed a lot of work. Here's the first revision on E40 for comparison I installed yesterday.

Motiv had a FlexFuel kit with ethanol sensor, but you can put together your own without much effort.

That doesn't show a shift though. If it's anything like the previous log then you're not really getting the benefit of the DCT, even a slushbox would be putting power down better than that.

Next time I log I'll stay in it a few seconds after the shift to see how it recovers. I didn't have DSC fully disabled and torque limiter was kicking in also, but not sure how much that affected it.

Just realized both PI kits I have are running 550cc injectors. At least I believe they are since they have 52 etched into all of the injectors. There goes my hopes and dreams. haha

I don't use launch control, even now that I have XHp and have control over the launch RPM's it doesn't work well.
I just goes slow and easy into the floor with the pedal. Takes a few tries to see how you are hooking up.

Here's the most recent revision on E40 with 2048 tq lim delete. I shifted into 4th this time and kept my foot in it a second which was enough for around 9 mph.

Your HPFP is still tanking before picking up,

Have you installed PI and done LPFP upgrade yet, before this log was done?

You went WOT from 1800rpm, would advise against that, go WOT from 2500rpm in future logs.

This log looks like you have a crap tone of lag (almost 1400rpm before reaching near boost target) its possible your turbos are tired.

Shift looks much better there

Rail pressure is dropping early on though

Waiting on parts for the PI, so held off on both it and the LPFP. The ethanol content was a little high on the last log. I added some 93 before the most recent log.

Didn't realize until now I'd started so low in the rpm's on that log. Won't do that again, thanks. I was dodging semi trucks from the emergency lane - sketchy.
