Error Codes After Tune....p0236 P0238 P0420....

[mikrad]

G'day guys.

Just got my FG tuned and got a nice 308.4rwkw with injectors, cat, pwr cooler, PW piping kit, herrod cold air intake and walbro fuel pump.

On the dyno there were no dramas, and on the test drive it was just great.

That evening, went for a bit of a fang and when I hit boost and a bit of revs I got beeping alarm saying "system comms fault" and "dsc fault".

At the same time came up the little yellow engine light. Reading into what I could from the manual it said that is just because of the emissions now not being met. Not a huge concern to me but I wish the light wasn't on.

I plugged the xcal in and had three error codes:

P0236 - turbo boost sensor A circuit range/performance

P0238 - turbo boost sensor A circuit high

P0420 - catalyst system efficiency below threshold

To me, the first two sound like "well of course you are running more boost now the sensors are reading high"

And with the cat one, "well it's a high flow cat it makes sense that it thinks that"

Given that I don't want the alarms beeping everytime I hit some boost (which is only 14psi), and that every man and his dog get their XR6 tuned and don't get these errors, shouldn't these have been disabled when it was tuned?

A part of me worries that there is a problem with the car but given the fact it was only just tuned on Thu and immediately gave these faults, surely the tuner missed a step?

I'm waiting on him to get back to me as he says it's the first time he's heard of those error codes, please let me know if you've ever come across this scenario!

Thanks in advance for any feedback!

Tune needs work.

Look I don't want to name names cause that's not fair but it was a top tuner here in Melbourne, so that's what got me wondering why I am having these issues when I'm sure there have been heaps before me.

I'll wait to hear back hopefully Monday it's more of a pain in the ass and makes me worry every time I get on the gas.

Tell me your not from dubbo?

[JETURBO]

Then stay off it, fair simple huh

[Ralph Wiggum]

The first two codes are ford tuning 101 if tge the tuner is experienced tuner my assumption would be that they forgot to make the changes

[mikrad]

Thank Ralph for that
