Has there been any firmware update or work around for this.? Basically the first start, when the wideband is on htr, the car runs pretty bad until it displays the actual afr, then it runs normal. I heard the only work around was the newest adaptronic or unplugging the serial in for the wideband.

 

I dont think you should start your car until your sensor is fully heated. It can cause your O2 sensors to fail prematurely.

I would guess that the WB is is sending out a full lean signal, and your ECU has AFR compensation turned on. Its probably dumping in all kinds of fuel until the sensor gets a reading.

This is just a guess. I know nothing about Adaptronic.

 

Well even if you let it heat until cranking, as soon as you crank and start it goes back to heat mode until it starts reading the afr.

 

You dont have your WBO2 connected correctly then.

 

Sounds like a temperature correction issues as well. I can start my car fine both in closed loop and open loop without waiting for the wide band. You can tell the ecu to start in closed loop after a certain coolant temp set point has been reached.

There is nothing wrong with your innovative or adaptronic hardware I would say.

 

care to elaborate? My car does the same as the op.

 

Yea, if there is a way to have it stay connected while cranking that would be great, haven't really tried looking for a wire like that yet though. Also found my serial connector that goes from gauge to ecu was severed so might have been causing some issues. Have a new one ordered already.

 

I have tried letting the sensor warm up first before I crank but the car pulls the power from it once I start cranking so I have to wait for the sensor to warm up/initialize again and the car runs rough till the wideband kicks in. Kinda lame

 

Exactly how mine reacts. I've heard the newer adaptronic model doesn't see this issue.

 

Yeah, your wideband does not affect your startup/crank map at all. So there should not be a need for the wideband to be on while cranking.

It is actually in the Innovate's manual to not "pre-warm" your sensor. http://www.innovatemotorsports.com/s...C-1_Manual.pdf
Page 5, or search "warm"

You need to tweak your cranking map and your temp correction or post start enrichment.
Looking at my old logs, my sensor shows AFR when the motor tries to catch, and within seconds of startup/catch.

 

So here is the part that would through that explanation out the door. You say that the wideband does nothing for the engine and it is the crank or temp maps, but I have a turbo timer that keeps the engine on for another 20-30 seconds. At this time the wideband would not be on, and clearly can see the engine rev up and go a bit crazy from the ecu trying to adjust to an error reading. Maybe I'll try and wire it to the turbo timer harness..

 

Probably need to check your idle. My idle runs perfect without the innovate while it's warming up. Hot or cold engine. I spent quite a bit of time tuning the idle.

 

Are you in open or closed loop?

 

Closed loop

 

WB02 can affect engine on startup.

Post start enrichment map adds fuel to base map.

WB02 Correction or AFR correction adds or subtracts fuel to compensate for target AFR.

If your WB doesnt affect your idle it could be because you dont have O2 correction activated.

 

If wired correctly, a turbo timer would keep everything on. Why would your wideband turn off?
If your wideband is wired to a different 12V source and 12vIgnition then sure it could be off.

Now think about it this way, if your wideband was faulty, what would it do? Go into open loop. Which would look at all your adjustment maps, your water temp correction, air temp correction etc.
Referencing your original post, you said the only way to solve it was to remove the serial, which would mean no wideband, same thing, all the corrections maps are going to be searched.

I would say put your car in open loop, and fix your correction maps to get close to the correct AFR. Back when Widebands AFRs were relatively expensive, you would tune everything to match the target AFR, there was no closed loop tuning. Closed loop is a safety precaution, but the basics still need to be setup.
I come from using a microtech without closeloop, but had a wideband for "display" and dyno purpose.
