basically I have to give up on my bigger and better plans and keep my turbo stock till I can save up some significant money for a number of other things.

anyhoo Im shopping for a wideband that I can use until I can afford to go with the full haltech e8 setup.

basically I need it to be able to feed the stock ECU as well as a guage in the cabin, and if possibly have an alarm function for minimum/max afr so I don thave to stare at the guage constantly

any fingers in the right direction would be fabulas thanks

for reference what my setup will be
large street port
walbro, KG rails/-6an lines, 720 secondaries
RB revII exhaust
FCD
think thats the important stuff



oo second question
can after market boost guages be connected to the stock Ecu for a signal, or do they require their own boost sensor?

 

just go with the AEM wideband kit.. this way u can look at the lights quickly and know where u are..

295.00 shipped from me!

 

i was gonna say the same

 

**** AEM widebands, truly. my only experience with them led me to believe they are useless for most rotary engine tuning. why? because the unit i worked with only went to 11:1 before being useless, sub 11:1 is where you should be starting your tune on a rotary not working your way down to it... hopefully not all of their widebands are this way but i was disappointed when trying to work with this particular new model.

i suggest an LC1 innovate wideband, it can also emulate a narrowband input that you can wire into your stock ECU to retain closed loop operation and for those standalones that still use the outdated narrowband input for datalogging purposes without need to reconfigure the EMS or run a seperate datalog for AFRs.

 

I have a PLX M300. It's got a narrowband and wideband output so you can hook directly to your ECU. He Innovative LC-1 is nice if you want something fancy looking.

 

You don't need it to send a signal to the ECU. You leave the stock sensor to do that, and add a wideband sensor downstream, usually at the bottom of the downpipe to protect it from excessive exhaust temps.

 

i got an AEM one and will on the one hand monitor the afr's with the wideband output and on the other hand connect the narrowband output to the wire of the stock sensor, so the stocker can be taken away! i think that should ork fine.

as far as the position of the sensor is concerned: i was worried that the extremely high exhaust temps of the 13b would kill my sensor so i'm actually tryin' to mount it as far awy from the turbo as possible! do you think 20inches down the pipe is safe enough??

 

If the stock one is there, and works, why do anything to it?

 

'cause i'm doing 3" exhaust, so the flanche for the stock sensor is no more available (plus the wire for the stock sensor is torn)!

 

thanks for all the imput guys

 

You could always install a bung just prior to the mufflers. Your going to get the same reading as at the bottom of the downpipe and it's much cooler there. You can run the harness up thru the cover over the fuel pump for ease of installation.

 

Innovate LC1 w/ XD16 Gauge - only way to go. Has been accurate and is still successfully in use.

I did a lot of research before purchasing this too. PLX and Innovate seem to be the popular good ones. People with AEM always had some sort of complaint about readings or something of that sort.

I went LC1 with the gauge and definitely recommend it for anyone wanting a good accurate well made device.

 

that would be a good idea, unfortunately i'm using a sport-catalyzer to prevent being busted by the swiss police
so i think that cat would falsify the readings of the sensor. i'll have to put the senor right before the cat (approx. 20 inches from the turbo)! hope that is far enough...

 

My bad. I should have mentioned no catalytic converter allowed if done that way. I've located the sensor in several places. One was just prior to the left muffler, one time in the stock position and later welded a bung inches from where the Racing Beat downpipe meets the next connection (cat or pre-silencer, depending on circumstances).

I used a NTK L1L3 sensor with a TechEdge version 1.1 wideband and have NEVER had a failure using that sensor, even when it was located in the stock 02 positon. Unfortunaltly TechEdge now uses other sensors than the NTK these days with their units.

 

really? huh...must've been a bad unit

 

+1!!!!
