Ken and I are working on our PS2 locally
This is 92 octane e10, with 70% meth spraying, but I think I had it spraying very late

I have a 3rd gear log with way less corrections when I had the meth coming out sooner and 'heavier'

This is easier to look at.

The car is doing what it was designed to do. So I wouldn't worry too much.

Fuel quality is very important if you want to make power with minimal corrections.

Another thing to note is that a lot of Euro Performance cars have a lot of corrections from the factory by default, even on 93, and that to actually get the car to run tip top condition, you have to run race gas, then it will feel like a bat out of hell

Example: if you have a custom tune for 91 octane, run 93 or higher if you never want to see any corrections, seems like common sense, but there you have it lol

No breakup or misfires... Power delivery is really smooth... Adding more boost. Will try to get more logs tomorrow.

Pure Turbos Stage 2 is by far the best thing you can do for your N55.

Ken,
What fuel are you using? How much E85 are you able to run with stage 2 LPFP and stock HPFP and PS2? When will you be adding PI? I love my PS2 and the MHD pump gas map you made me, am trying to decide what to do next for better fueling.

This is great news because if everything works out I'll have my PS2 installed this weekend and will be excited to have a tune for it.

Last time he mentioned he was on pump with 1 gallon of pure methanol in the tank

There isnt a aftermarket option for the hpfp at all that.

OK, thanks Rob. I thought he was running some % of E85 since he has a stage 2 LPFP. He also said he was going to install PI soon. I'm trying to decide whether to upgrade LPFP now and add PI later, or wait until I can do it all at once. I would like to be able to run 100% E85 if possible with PS2.

Here in Portland we have 92 Oct with 10% ethanol. I spiked the tank with 1 gal of pure methanol to bring the content up to @ 16% ethanol/methanol and octane rating @ 93.

PI should be installed in another 2 weeks. Will increase ethanol content and raise the bar once I have adequate fueling.

Thanks for the positive feedback. Always a good feeling. :-)

Well a upgraded lpfp is required to run PI, so sooner the better on it

boostconcepts.net, buy a core on ebay and save some money

Ken,

With flash-only tune via MHD how will you control the PI? Consensus on another board seems to be that most N55s w/ Fuel-It PI are controlling it with JB4, which has built-in support for PI, and that without JB4 a separate PI controller is needed which will need to be reflashed whenever you change maps. Is that true? Will you need to buy a separate AIC6 controller for your car to install along with your new PI? How much does that thing cost and where does it go? Will your MHD tune flash the controller too or is there a separate process for that?

Drop down menu to flash only

Or ball out and get Haltech ;p

[Rob_BMW_PNW]

It tapes into your TMAP sensor, similar to how some meth kits do it

You'll just get the standalone flash only kit. You can put a toggle switch on the AIC6 to turn it off when you don't need it.

So no need to reflash the AIC6 when changing maps?


My indy shop who does all my mods said if I add PI and run 100% E85 I might need to upgrade my transmission next. WTF???

The mod bug strikes again.. hahaha It's a good thing they don't have a clue.

You'll want to put a toggle switch on the power line for the PI so you can turn it off. You won't need it enable when you're running pump. Only when you fill up with E85 will you turn it on and use the port injection.

OK, so when switching from pump to E85 you just change maps and switch on the PI. No need to reflash the AIC6 then? Wonder what that guy on the other board was talking about when he said that.

So if I have PS2, PI and stage 2 LPFP, and maps for pump gas and E85, what do I do when running lower % of ethanol, due to seasonal variations in E85 ethanol content or when I need to fill up with E85 but tank has some pump gas in it (or vice versa)? Do I use pump gas map or E85 map, or would I need a third map for intermediate blends?

These cars run 99.9% in closed loop fueling, meaning the DME will always try to target AFRs set by the tuner. DME can correct up to 35% +/-

You could run a pump map and have like E40 in the tank and be fine, and probably not have any correction either due to the higher octane

OK thanks, good to know. Up to E40 on a pump gas map. And how low of a %E can you run on a E85 map? Down to E50?

Depends on how aggressive the map is, E70 is probably the lowest I would go, you'll see more corrections.

I use meth injection (via chargepipe), like 80% mix (currently), probably higher to help bump my octane, not for tons of power, but for cooler IATs and better octane rating.

Edit
Fuel it has a install and setup guide for the AIC6 btw.

Do you have IDC control from the AIC6 program (whatever it is called)?

In that case instead of an E85 map would it be a better idea to make an E70 map that could run on anything from E50-E85 (or something like that)?
