I would use stock injector flow rates to start with. Change B4349 to make up for the difference in throttle body sizes. C6301 map scaler needs to be changed also.

I am not sure injector flow is 1...

I had similar problems and running a c5 corvette with 1750 hp on my daily driver. I am sure you had to install large injectors and rescaled the injector flow rate. If you did I had to go back to the...

Thank you for the reply. I did make a typo in the 4307 table. I used calc airflow rate grams/s in data tab. In the column I ran calc airflow rate grams/s (dynair)and in the row tab I ran ect.

I have same corvette with diff mods and never saw this one before.

Thanks for the info.

So you did not go by manufactured specs? What size injectors are you using?

Does this mean you estimated what your meth injection added on top of your injectors?

Please...

To be honest I dont want to try anything unless its a sure thing. When Im only at 60% throttle 4500 rpms and see 2.33 grams and afr goes to 17 or so then reduced power mode...

Just hit 2.33 grams/sec tonite and sure enough goes lean and reduced power mode. I would not bother trying any of these alleged fixes for this unless its a proven fix.

Would be nice if maybe the...

I am running olsd and 24 lbs of boost. I can't seem to get past 2.33 g/sec before I see reduced power mode. I have seen one gentleman state this was his fix below. I also tried using dfe1 C6101 map...

Thanks guys for all your comments. I will start another thread for my last issue.

Thank you all for your comments.

Changing B4403 for 90 mm tb worked out my idle very nicely. I just multiplied it by 1.44 and dynair and iacdes_B are much closer now. I actually had to bring B4349...

Thank you for your reply.

Tried researching this issue and could not find anything.

My LM-1 meter reads rich but is smooth and consistent. The program sees afr from 12.5-16 or so in frame to frame. If I adjust the ve...

Finally found the culprit. I don't like leaving a thread hanging so here it is.

Hello and thank you for the reply.

I had my LM-1 connected to my car working with no problems. I moved it to another vehicle and selected the usual pids and my wide band still would not read. I selected more info in the pid selection...

Hello.

Here is the results changing B4349 table from .0136 to .0310.

I went up slowly while the car was still warm. (Worried about hign screaming starts) At .0255 I could see iacdes_B .85...

Hello.

Im pretty sure in some of the previous logs I posted had TPS error code in it.

First 30 minutes were 14.5 and running real strong then the water temp hits 80C and I would see AFR go...

Hello and than you for the reply.

I can see the diff and have tried the same but startup screams 4-5000 rpms.

Is there anything you can see in my tune that would cause this?

Am I suppose...

Hello gentlemen.

I dont know what everyone is doing to make the B4349 table work when they are using .0320, .0330 and .0355 but every one of those makes my car start at 4-5000 rpms. I put all...
