i need some first hand personal opinions about what wideband i should buy for my FC. AEM seems to be the cheapest but there's no way to reset it before each use, atleast not that i've seen.

in school when using a 5 gas machine we had to measure outside regular old Cali air and then probe the cars exhaust. that way we got a accurate A/F measurement.

i've seen a few that will "reset" like that but i dunno how goodthey are and for the most part AEM makes some pretty nice stuff. so opinions please, lets here them.

 

i havent heard good things about the aem. ive personally used the inovate lc-1, better than the aem as far as i know.

but if youre planning on doing any datalogging on datalogit, save yourself the headache and get the innovate.

 

my aem calibrates itself each time power is put to it.... its legit

 

I would go with the Innovate.

AEM is packaged pretty, but is usually a rebadged part...

If you want something to "look" cool, go with AEM.

If you want a more accurate product, go with the innovate.

When you order, do yourself a favor and order a second 5-wire O2 sensor, just to have as back up.

 

i used the zeitronix zt-2. it does datalogging, it does calibration. it does all those pretty graphs like boost and rpm and temps and so on, and its pretty cheap.

i sold mine but only because the haltech ps2k handles all that stuff now

 

plx devices.

check it out.

(Id show you pics but i sold it)

 

this is exactly the sort of info i was looking for, thanks guys. Davedge, what did you mean by rebadged? And RussTII, i checked plx out, it looks and sounds pretty cool but do you have to buy a gauge seperately or did i miss something?

 

A lot of companies don't actually manufacture their parts. They have a company(like innovate) manufacture the parts, and rebadge them from the manufacturer, so they look like they are an original product.

But then any technical support you may need, you would have to call around, untill you have the actual manufacturer of the part.

Even Haltech WBO2 controllers/gauges are made by Innovate, but directly interface with the ECU.

If I was to buy a product, I would want to buy from the original manufacturer, and use their tech. support when necessary. At AEM, chances are, you'll get a 20 year old kid that knows less than you do about the given product, and you are calling them for help?

 

for plx devices you have to buy some type of display module to go with the sensor module. you can get the DM-5 and display just the wideband readings or a DM100 or 200 and have the ability to daisy chain up to 32 other sensor modules (oil press/oil temp/boost/egt/etc) into 1 gauge. but i believe you can only display 4 at a time.

 

Haltech broke ranks with Innovate several years ago. Personally, in dealing with them it was a welcome change. We've had several customers with problems with their LC-1 units. The A/D converters like to crap out on them. Innovate was always good about repairing them, but...

I'd certainly recommend you look at different options. The NGK AFX gets high marks as a good budget controller, though it has the clunky box/display. The NGK is made by ECM, which makes high end, lab grade controllers used by OEMs and the like. FJO makes a nice unit. The new Haltech controller has been working very well for us as well.

I recommend going over to EFI-101.com and reading their board and looking for input from the professional tuners on what works and what doesn't.

i remember reading that awhile back. i have an old aem that im not to happy with. but the newer ones seem nice. (mine doesnt read below 11.1 on the gauge, but itll sent out lower then that for datalogging)

i think some choice depends on your standalone or what your using for datalogging. now that i have a haltech it doesnt get along with my aem wideband. but on my s14 with aem ems, the aem had no issues. was great for doing autotune on it and compared to the dyno at UMS it was correct.

note that so far on aem ems and haltech your calibration of the wideband is done on the ems

 

Not entirely true... when I was doing tech at Haltech, we changed the range/outputs to work with Haltech ECU's before we shipped the controllers out.

Not sure what's going on now, since the move to Kentucky or wherever.

 

This.

ALOT of tuners swear by it.

I've heard mixed things about aem products in general. I'm not saying aem is crap or trash. Their stuff just seems inconsistent.

 

wideband is used to tell you the afr... a aem does just that. set your map on your standalone and it puts that amount of fuel into the motor. then it gets burned and you get the reading on the wideband.

if you havent used a product dont even talk about it
