APR stage 3 ECU ?

[sti4now]

I have an APR chip for my APR fuel kit and APR K04's. I was wondering what the boost will be set to if I put in 100 oct and go to the RACE map mode. Just let me know thanks

19-21 lbs.. apr's race file does not raise the boost..

omg, are you still going on about raising the boost?

[sti4now]

^I was just wandering what all would be changed (timing, boost etc) I am new to the S4 world, so I would appreciate being informed rather than flamed.

Ok thats fine. The race file will change timing more than boost. I seem to remember on MDS4 race file the boost actually drops but the timing increases.

[sti4now]

^ was there a noticeable difference?

[Evilevo]

O yea there is a noticable difference.

This is correct.. its not all about boooosttt !

[SpoolPastYou]

go VAST

[Audone]

^Very useful...

While Vast has great software.. you're APR stuff can run dare I say just as fast with a few lemmi-tweaks....

I love my APR stage 3 software. It put down some great numbers on a local dyno.

I run 104 map with 100 octane and meth, works great.

[sti4now]

^could I safely run the 104 map with 100oct? Also could I go VAST with APR fueling?

NO! you need 104 oct to run 104 or 100 oct and meth.. Vast does have a file to run rs4 injectors but you still need to change out the maf/housing and the fpr I think.. I think the total cost of the switch over was around 1500 iirc..

Are you kidding?

Can I put a square in a round hole?

[sti4now]

Can I run the race map with 93+ meth?

[ms4cd]

No

[DraxeofDclan]

Im in progress(slowly) of going stage 3 from stage 2. Glad I didnt ask those questions.....although I'd just buy Xylene and add it to CA 91oct to boost enough to use 93file. I question if adding 45% or 1:2.5 would boost enough to run 100octfile.

[///M3 TO S4]

No

uh...yes. Meth combined with 93 makes OVER 105 octane. So tell me why a map for 104 wont work?

[DxC]

hey sti4now i have APR stage 3 too so feel free to ask me any questions. ill try my best not to flame u since youre a n00b ... but no promises

heres some logs of pump file vs race file ...

[/QUOTE]

What software do you use to graph those results. APR ECU Explorer? Looks like the only diff. is the timing. All other results are pretty close to being the same. Im looking to go stage 3 so any help would be great. I much rather plug n play.....not tweak or have a custom remapping. Perhaps you could part with some items.

[DxC]

yea ECUX ... and this really cool guy named MarkP on Audiworld made these macros and templates ... this other cool dude named nyet made this program called ecuxplot which is like an evolution on it.

pretty cool huh?

I think you'd benefit from a custom tune from the way it sounds as you want more power. VAST can custom tune you based off of logs sent back etc etc. Free revisions for life with the fueling kit is pretty nice too

[sti4now]

I wish people could answer questions without flaming..Thank you DXC, much appreciated

Do you have the APR stage 3?

I logged and found out that with 50/50 WM you CAN NOT run 100 map with 93 octane gas. Safely.

If you do not give a shit you can do 87 with 104 map so I guess you were right. It is possible.

100 is the MINIMUM octane for the 100 map, meth + 93 octane would be WELL over 100 octane....what's so hard to understand about that? And what logical explanation would cause it not to run right? If anything you should be able to tweak it for more timing. You obviously had something wrong with your car if you logged your car and still came up with that conclusion....

Nothing wrong with my car. The timing CF's were way too high to run 100 map. That's all.

I think you don't understand Water/Methanol injection and how it works. You are cooling the intake temperature, and altering the tendency to detonate somewhat. You are NOT raising octane to 100+, or producing an equivalent effect.

[sti4now]

Just talked to Chris at APR, and it CAN be done, just do some data logging to make sure the motor running efficiently without pings and knock. Could always run the 93 pump map with meth then throw in some 100+meth and run the race map

[audi666]

hmm ive been spiking around 24 on my stage 3 apr. im still a bit confused on how everyone else is a bit lower.

[sti4now]

I spike around 23, but hold 19ish
