ok..

i'm buying an s5 engine for my s4... but i'm getting no computer or wiring harness...


i want go standalone... i figure i'll make this engine as badass as possible

so what would a good standalone be?

price really isn't that big of an issue

 

Well, if price isn't an issue....Motec would be a good place to start: http://www.motec.com

But it seems to me that you're a beginner, so you probably want something with more support. Check out the Haltech in that case.

I'm partial to the Microtech, but there is less support and it's slightly less versatile then the Haltech.

If you are into DIY, the Megasquirt works quite well, but is far from plug and play (of course, none of the above are plug and play either).

 

I'm not sure about haltech and motec, but the microtech is easy to install. and a problem with motec is no one around hear *florida* knows how to tune them. So that may be a good idea to look around where you live to see who tunes what.

 

Haltech would be a good choice.

www.performanceconceptsonline.com has a big sale on Haltech's going on right now and you WON'T be able to beat his prices!! Hope that helps some.

I've been eying that ebay auction myself for the S5 TII swap.....I'm 95% sure I'm going to be buying that one.

 

I'd rather buy from a seller that I trust instead of Ebay. It's worth the extra money to know that I won't get ripped off. Just my .02

 

Got haltech on my duece, and my buddy has a wolf 3d.. I think wolf is a bit better and has more settings/options.. really like that handheld. But both are good.

 

I had a quick question about tuning a standalone. Do you need to get some sort of wideband sensor to keep an eye on your fuel a/r's? Or is the only way to properly tune one is to go to a dyno?

 

road tune with wide band and egt sensor should be fine.. but dyno will yelled you most power.

 

how come i havent heard anything about the autronic yet? nobody willing to cross the bridge?

 

Here's what you want to do: Go to your tuner (if you don't have one yet, get one first), and ask them what they're the most familiar with. Apparently cost isn't a concern, so find a reputable tuner, and let them work their magic on the system they're most comfortable with..


that said: +1 for DIY MegaSquirt!

 

A bit more support in the RX-7 world. You can probably count on one hand the number of people here running a Motec.

 

Zkeller put one on his third gen... that thing is friggin AWESOME... it blows Haltech's and Microtechs right out of the friggin water. SOOO many functions.. SOOO much easier to tune... the tuning software has realtime graphic display of engine parameters.. i used to stand there and over that thing everytime i went in his garage!

The only thing that kept me from upgrading my haltech to an autronic was the PRICE... YYYYYYEEEEEEEEOOOOOOOWWWWW

He was also the ginuea pig for the Rotary Autotune function..... (the had autotune out for other cars, but it took a while for the rotary version)... There were some bugs with it, and i think the got it fixed... BUT... he got scared of himself running 20+ PSI of boost all the time and ripped the motor out of the car and did the LS-1 Swap.. SO... I have no idea what his final verdict on the Autotune function was!

I do know that our GENERAL idea about the autotune was that it was REAL nice for setting cruising and light throttle settings. HOWEVER... it had do be in a certain "Box" (the box i'm talking about kinda like the numeric fuel maps for a haltech set in an excel spreadsheet, but much better)for a certain amount of time for the autotune function to work and when your hammer down and RPMS and Boost are going apeshit, theres not enough dwell time per box.

 

You need a wideband O2 sensor wether you tune on a dyno or on the street.

 

As stated above.. a dyno will usually have a wideband if they are going to tune your car, not just do a HP run....

if you get a standalone, its almost a MUST that you also get a wideband, especially since you can get an LM-1 for less that 400 bucks. Unless you want to traielr the car to the tuner and spend 150+ bUcks and hour to have him totally tune the car on the dyno.. which would take a whole friggin day to tune EVERYthing....


My Method for boost fuel setting

Innovate LM-1 Wideband..

Output cable of LM-1 goes to Haltech... Set haltech to Datalog...

Other output of LM-1 goes to Innovate A/F gauge on a-pillar below boost gauge, LM-1 itself in middle of dash.

Put car in third gear at about 3000 RPM
Press "M" on Laptop to datalog to memory, and stomp on it!!! Watch A/F gauge to make sure I'm somewhere close to 12 (it shows leaner tha it is, so 12 is kosher... its an analog needle anyway..) when the shift light comes on, drop to 5th and hit the space bar..

Pull off at next exit and eyeball the datalog and take fuel out a little bit at a time..

Repeat!!!

 

Motecs are fanatasic. Its what a BUNCH of guys in Northen Minnesota run and they abosolutely love it.

I recommend it as well.

 

lol!! Thats the exact method I use.. How funny...

 

I vote for wolf3d V4 with a handheld controler, and an innovate LM-1 (lm-1 groupbuy neone?)

Check the wolf3d section, or pm me with any wolf specific questions, ill answer or pass them along to someone who can

Thats only coz most peeps here aint rich like bunnybunny and dont have like $10,000 to spend on a Motec. If I was rich Id have Motec everything.

Dont all ems have that? Teh Haltech and Microtech websites show realtime graphic displays.

If thats true then howd peeps tune engines back when there werent any such thing as wideband O2 sensors? I know theres been car engines a long time befor wideband O2 sensors invented.

 

haha!!!!

me? rich?

i'm almost flat broke... except for about 500-600

but i'm working my little *** off to get everything for my 7

and plus, i don't an s5 ecu or anything, and i want to squeeze as much out of this thing as i can

no matter if i have to spend every penny i earn on it
