Easy and cheap engine management... Is there such a thing? - Subaru Impreza GC8 & RS Forum & Community: RS25.com

jeffesaurusrex · 06-23-2009, 11:13 AM

I've been studying engine management options for my turbo kit. I haven't decided whether I am going to get a Ludespeed kit or try and build a kit from OEM parts + aftermarket up/downpipes but that isn't the issue here... What I am wondering about is what can I do for an ECU?

Previously I was looking at keeping the stock ECU and buying a J&S safeguard, maybe S-AFC and calling it a day but I was looking at this PerfectPower 6 ECU and I got to thinking: does this have knock control or similar already onboard? If so I can use this and it will be much less ghetto.

I was thinking about getting this PP6 and the 2.5bar map sensor instead of voltage clamp, but i don't know if I can do it or not. Is it plug and play or do I have to wire the entire thing up? I am confident in my mechanical ability as far as getting the turbo installed/oil and coolant ran/ect but when it comes to electrical I fear I am fucked.

Is there anything that is plug n play for under 600 bucks (about what I was going to spend for J&S safeguard/S-AFC)

TL;DR: What EM options do I have that aren't a million bucks and are pretty easy to do?

PS: Car is a 2000 2.5RS 5spd.

$600 could probably get you an ecotec tune or some other open source tune..

I got an EManage Ultimate for $400 used off of ebay. Coupled with a $20 used GM 2-Bar MAP sensor.
The AEM F/IC is a "potential" option, if you're willing to risk the possibility of the misfire issue they have with "some" of our cars.

Where do you live?

I am close to getting my PP6 working. The problem is that Perfect Power has crappy wiring diagrams. I have good ones including the ECU pinout for your car I can send you.

Search for megasquirt.

The megasquirt is a full standalone. I think he wants to do as little wiring as possible.

Yes sir, and I live far away from anyone that could tune it (unless there is someone in Indianapolis, Chicago has a place but Chicago is 4hrs from here).

Someone has offered me a Greddy Emanage all pre wired, do I need knock control with this?

Also I didn't know about the misfire problem, thanks for the info. I need to avoid getting something that doesn't work because I'm on a limited budget, if I buy something that doesn't work it will screw me up and I will have to wait to finish it and I can't have my car down for months.

Thanks for the info so far!

Limited by budget usually ends up with a broken car and no other forms of transportation. Do it right, or don't do it.

There are a great number of resources here and on nasioc where you can learn from others' mistakes. I can think of two epic quotes that sum up your situation:

"If you can't afford to do it right....you can't afford to do it."

" Cheap...Easy...Reliable....... ...Pick any 2."
