pings on hard accel

[matt]

Oh ya and now my P.S is getting noisy when hot 2 days in a row . e36 pump with e30 rack .

You're low on fluid.

Your O2 sensor and knock sensors and MAF are all suspect.

Chips don't adjust anything based on octane. If it detects knock events, it pulls timing. It then puts it back, until it detects more knock events. No permanent or temporary "correction" factor is applied to prevent knock. (unlike O2 sensor feedback)

Every sensor is new from BMW when I did the obd 2 to 1 conversion .

What about the Intake Air Temperature sensor? A bunch of OBDI guys on bimmerforums had the same pinging until they replaced the IAT.

[ericzz]

That my friend is the only one I never changed looks like I will give it a try .

[matt]

Did you find any codes?

[ericzz]

No code in it . I called turner they checked the chip to my specs no conflicts. I tried it with zero air filte rthinking it may be to small no change . Installed a can of 104 octane boost no change . I will order a sensor in the morning hope they stock it ! . I also installed a power steering cooling and it seems to have corrected the steering issue .will advise in a few days .

[ericzz]

Sensor made no difference . Should I call turner for a down tuned chip less advance ?

[matt]

Are you sure you're actually hearing pinging and not some other sort of noise?

[ericzz]

OH It's pinging no ? .
Let me mention one more thing I am running the OB2 valve cover I basicly matted the factory OBD2 pvc hose to the OBD1 pvc hose so in a sense I am running no PVC valve . I know the valve on the OBD1 system is at the valvre cover connection and on the OBD2 in under the intake could this cause it to ping not to have a PVC valve ?

[bdi_fc]

I have this same issue, but I was hoping it was just the IAT. If it's not, it must be the turner chip because we both have it along with the euro/540 hfm and 24lb injectors.

I'm thinking the chip was originally intended for a 3.0 and isn't working well with my 3.2.

[ericzz]

I called TURNER they are sending me a trial chip .

[ericzz]

antiknock chip still pings ! WOW I am at a loss! I will try a lower tstat see if a lower temp can help .

[matt]

A lot of oil vapor in the intake charge can definitely cause pinging, but your motor would have to have massive amounts of blowby to have that issue.

Very strange.

[SchnellerVert]

Maybe a quick drive up to Amesbury is warrantied. You are positive it's pinging? and not something else making noise?

Let me know what you find out. I'm in a similar situation.
