At WOT my AEM wideband AF goes from 14-16 down to 10.00. Probably lower as 10 is the lowest it would go. Should I go to Technosquare & have the ECU reflashed? Mine was previously reflashed by TS before I installed the TN so it would only be reflash charge. Has anyone done this before? I have the TN for 5AT w/ cat. Also, any danger running this low?

Thanks,
Jeff

 

Don't bother with a reflash, get a Utec ot a EU.

 

Yeah if you see my first threads with my Turbonetics kit (if you do a search with threads that I have done in the Forced Induction Section you will the see them at my graphs along with thoughts/theories and what I ended up doing about it), I had similar issues with going rich... Into low-mid 9's at around 5K rpm

Sent my ECU a couple of times to Technosquare, they tried to help but didn't work out.

So I went with the Greddy E-Manage Ultimate, but you can get the TurboXS UTEC now

 

Keep in mind that the cat on your car is causing a restriction and causing the car to run a little richer. Could you get it flashed again...sure...but theres nothing wrong with being a little too rich..

 

Oh yeah better to be a little more rich than lean

But like in my case, damn you could feel the power tapper off after 5K cause of the fuel.

 

ya, how does it feel up top?

 

Knowing you have the cat, I was about to suggest the same thing... Of course, you'd think the particular flash would compensate for it. You are making good power, right? The last I heard you were making 360+whp which is very respectable for a cat kit on 5at.

 

Yes, that is correct...when I initially got the car the AF was running 10.5 at WOT & that was the resulting dyno. However, after 2 weeks my AF started to dip to 10 & possibly lower which at that time I started to feel a loss of power (butt dyno). I also started to have those CEL lights P1273 & P1284 (O2 sensors). Brought it back to Danzio Performance last week & they called TN if they wanted my ECU back. However, TN recommended trying Technosquare. I have an appointment with Tadashi on Monday (might as well take a shot since I'm local). We'll see if that helps...if not Utec might be my only alternative.

Mia - Do we have a good Utec tuner here in So. Cal that's familiar with the TN?

Peking - Good read on your post on this.....really helps when we can share these experiences & we don't end up lost.

Thanks guys....do appreciate your help!!!

 

I don't think the ECU would just adjust like that. Has there been any significant change in weather?

 

Le us know if you ever get rid of those dreaded codes. P1274, P1283 Tried a bunch of different things and still can't get rid of them. After an ecu reset they just pop right back up.

 

GT motorsports in Rancho Cucomanga is a Utec tuner and has had some success with that..

 

+ another 1 for UTEC or anything else for that matter. I was running rich too, but for the money and time of a custom flash, you're better off just flashing back to stock and getting it tuned. Might cost more, but well worth it.

 

kill the cat!!!

 

and the mouse shall live happily ever after...

until another cat shows up in the hood atleast

 

Before it felt like ***, it would pull hard like a mother until I hit 5500 RPM then it goes like limp...

I had to do with another form of EMS, so went with the Greddy E-Manage Ultimate and upgraded the fuel injectors and went with the AAM Return Fuel Kit to knock two birds with one stone lol.


Yeah def. Also good thing you are local, when I sent my ECU to get re-flashed again by Technosquare... Overnight shipping costs back and forth to Technosquare was killing me
