I guess you technically could if the injectors were sized perfectly. You would still be failboat. I would expect this line of bs judging by half the posts i read.

The s kit is a nice setup. I installed mine last spring and drove around non intercooled until a couple of months ago. I planned ahead and picked up a greddy emanage with injector and timing control for about $275 used and also added a wideband and installed them before my kit arrived. (trust me, you'll have lots of time.)

These two items are must have equipment for turboing your nb, or at least some sort of fuel/timing device. You think your saving money, but when you blow your engine, think how much that's gonna run you.

I fully intend to run the kit "as it is" to validate BEGI's claims of it being a good solution. According to the phone calls that I had with their reps, they have ran the car as it was, no ic, with the begi FMU for an extended test duration with no issues. I do appreciate the suggestion of the Greddy management unit, but if I start throwing money at it in the future I will most likely look to brain for my MS solution and harnesses.

A little bit of research tells me the greddy unit is discontinued, do you still use it?

In b4 "omg so dumb engine blow up u dumb u dumb"

Mine only ran 140 at the wheels with a S kit however i dont believe the tunning was perfect as the intake was burning hot.

I first tried to run begis 1.5k piggy back (no injectors) but i was getting some shitty stuff. Like it would randomly go lean at idle... it would randomly go super rich at times.. etc so i gave up on that and went with a standalone...Been thinking of switching to MS my self...

Hey Toaster, how did your S kit work out? Been thinking of doing the same.

Couldnt tell you. It came in the mail but the chinacharger came without a wastegate actuator so I havent been too motivated to install it until I have the part.

I did get the FMU in the mail...its really strange though. Instead of being space ship shaped its a black box that says "Diy auto tune" on the side of it. Thats working pretty well.

Wow, been a while since you bought it? So you installed the FMU? Does it improve performance even withput the turbo?

Angrytoaster, see if you can switch to a real Garrett actuator rated around 7 psi.
I had issues with the chinese-made one that came with the kit when running low boost initially.

Toaster,

I'm stepping in because this wasn't made abundantly clear previously. YOUR CAR CANNOT RUN E85 WITHOUT A STANDALONE ECU. And once you have a standalone ecu you can either run regular gas OR e85 but not switch back and forth without retuning.

OEM Flexfuel cars you see running around that can handle both fuels have a special sensor that detects the concentration of ethanol and the special ecu compensates accordingly. None of this can be done with a stock ecu and fmu. Your car will not run if you try, and if it does it will be harmed. Cars running e85 require ~30% more fuel all of the time than regular gas cars. That means idling, cruising, accelerating, and boosting. You have no way to accomplish this with your current tools. I don't want you to be stuck somewhere on the side of a road right after you filled up.

You are welcome.

After tunning to E85 i also say bs. Stock ecu will not run E85. The main difference is its not a flat 30% scale. In other words if you add smaller injectors for good cruise, it will lean at higher loads. If you add bigger injectors for correct high load afrs, it will be rich at low loads.

<- the guy who bought that 1.5k piggy back from ya.

It's actually been great with 440's, that and throwing away all of the Begi maps and starting from scratch.

Glad to hear man, it made no sense to me why anything would happen when at idle i had 0s all over everything. Glad to see its running good for you.

He he, haw haw. Sorry for switching bait guys. Megasquirt is awesome, and I have seen the light. Just received some parts in the mail today from begi. I had hoped to start installing this weekend but some things have gotten in the way. Damnit.

In other news, sixshooter thanks for the disclaimer, I hadnt intended on running E85 as my connection fell through, and the gas station that I found on google maps no longer exists.

Ive been trying to tune the car N\A for now.

Can I ask a dumb question about the tune? How does my fuel table need to be altered when I am running the turbo? Should my AFR table and ignition table remain the same? Are there any other no-brainer options that I need to tick on or off in MS to not blow my **** apart? I do not want to be spoonfed, but are there any tips I could steal as to not wreck my ****?


Again, sorry about being gay for the FMU before, and thank you kind gentlemen for showing me otherwise.

You'll be tunning the upper load cells (+100kpa). You might need to tune the 0-100 a tiny bit and usually pull some timing for safety. For E85 there is a website that shows you all the stations that carry it via government documents instead of google that sometimes doesnt work. Throttle on and off transitions will need to be changed and possibly few other settings however i'm not running ms so i dont know all the exact details.

Makes sense about the upper load cells. For throttle on\off transitions, what do you mean? like altering the TPS calibration? Searched that e85 ****, somebody else linked me to govt website. The station exists on there too. I was so mad when I drove there for nothing
