Opinion on running w/ CEL (tuned + bolted on)
#16
yea. o2 can report many errors, voltage errors, heater circuit errors etc etc.
obviously bring it back to the tuner. he might have not turned off the correct code or forgot to load the corrected rom. Unless there is a new trick i dont know, its the PO420 you want disabled when you are running test pipes. Your CEL could also be something completely unrelated

yikes! is P0420 the master sensor (for lack of a better term - does it take care of all issues related to test pipes - high flow)? does that mean the other codes that the car was throwing were unrelated...? high voltage sounds right (obd). interesting...i'll let 'em know. should i go ahead and turn everything else back on then (minus P0420)? thanks for your help neal - sincerely appreciated!

I got a P2a03 about 60 miles after installing my FI HFC, which is different, im hoping i dont have an exhaust leak, does anyone know if that code would be any different. i cleared it the other day, and it still hasnt come back yet.

whatever the case, is is certainly not mentioned in the uprev manual. there is a "high detonation" map that is triggered when the knock sensor detects knock.
I am 80% sure a po420 does not pull any timing.

Any catalyst code will cause timing to be off.
Had a in depth conversation, any cel will cause loss in performance.
Why do you think it gets Disabled, when its tuned.
No matter if its test pipes or hfcs.
Dtc codes are disabled.
Ecu will not allow full power, it thinks there is a malfunction and does cut performance.
Btw prior to this tune ,my car hit limp mode w cel on another dyno, causing hp to dip & shift point @6600 rpms.

"any catalyst code will put timing off" is a far cry from "any CEL will pull 5 degrees of timing" if thats the case, then yea, of course the timing will be "off a bit"...its "off" when its a little too hot outside, or little too humid.
the DTC's get disabled because there is a list....and you just uncheck the codes you dont want to see any more...and you dont see them anymore
and just for ****s and giggles, I pulled 5 degrees of timing from my uprev map with RTT, my car was slower then my old civic. I did not loose timing, at least no where like that, when I had my Po420 enabled. I dont know what is going on with your car, but I have never seen timing pulled like that, or cars going into limp mode, in any of my own cars, or any of my friends cars who drive around for years with Po420 enabled.
if you have Po133, or any front (S1) O2 sensor codes, your car will go into "limp" mode and run continuously in open loop. everything will be haywire.
now unless you can post up data logs of your car before and after you disabled Po420, or can quote "chapter X, page Y, FSM/Engine managment texbook Z/Uprev manual", then I dont think I can change my mind based on "what some guy said". Im not saying your wrong, i'm just saying it hard to believe

Im having additional maps added.
Cat code causes ecu problems.
Wtf, why do i need that to prove to my car was in limp mode.
If dont need uprev to tell me that something was wrong.
im not going to argue, you are not a tuner.
Anyone driving with a cel light for years "your friend" as you ciaim, is an idiot.
you pulled 5 degrees yourself, it runs like crap.
Guess you never hit limp mode, never said the p0420 was the only code if ever had.
Had 1 for ecm & tps sensor, never came back on.
Ecu retards timing when cel is on, you are losing power.
5 degrees is them extreme, but it does occur.
Just becausee you claim it wasnt.
Notice how all gains come from Timing advance.?
Thanks bye now.

a Po420 will not enable the High detonation map and put you in limp mode. your statement "any CEL will retard timing" is wrong.
to be honest, your logic is just as bad as your grammar. I really don't think you understand me, or even know what your talking about. You seem to spread a lot of misinformation on the forum, and then when someone calls you out, you respond "k thnx bye". keep on trolling kid
