Could be a combination of a change in RPM, MAP, MAF, AFR when the trans downshifts and the RPM jumps? Best to post a log of what is occurring.

You are going to need the key to get in. You will have to hope the programmer is willing to give the key out. Given that they locked it I don't like your chances.

This was the first V8 chainsaw I had seen.

New year close now. Hope everyone had a great Christmas.

I picked the side that I had the miss on using the NBO2 sensors. When it would miss the voltages changed. Swapped leads from one side to the other and the changes I saw in the NBO2's changed sides as...

I read into your post that your issues started after you were off the dyno for a period? I know on my VY there is a ground connection hidden under the ABS module which has caused people trouble....

I will soon be installing a new cam in my VY Commodore (Manual, 5.7 LS1B). The cam is a VCM 21. It has been spun up and the specs are 217/227 @.050 .600" 579" LSA114 which is slightly different from...

If you are losing communications with the ECM is it losing power? Have you tried power and ground connections to ECM, battery, chassis or alternator? Do you have a log of the poor running up until it...

Double post.

B3647 is commanding a leaner mixture as that is what you are asking of it. Your units are in EQ ratio so less than 1 is leaner and greater than 1 is richer than the value you set in B3601 (Ratio of...

It would be a good idea to post your tune and logs. That will help diagnose the fault.

I don't claim to be a guru on the matter however I see it best to at least try the original heat range with a plain jane plug (my issue was fixed with a cheap set of champion plugs) and see if it...

Yeah only got my hands on that sort of stuff recently. To ask the silly questions the fuel pressure is ok and the injectors are not leaking? Maybe try hotter plugs? Hope you figure it out soon.

There is a spread sheet that I have used from the forum. Have a read of this thread.

You have given Joe screen shots of your EFILive Tune maps. What Joe wanted to see (as I read it) are the maps from the v7.5 EFILive Scan Tool. The maps you use when data logging.

I could not give you an AFR as I did not have the gear to measure at the time however definitely very very rich. Idle dropped from 750 - 800 down to maybe 400. Engine would only barely idle black...

I had an issue like this with a turbo charged RB30. It ended up being caused by a combination of the new iridium plugs I installed (took about 100km to play up badly) and the lower compression of the...

The PCM will run the engine in open loop until the engine comes up to the set temperature. Once that is reached it will go into closed loop and this can be monitored with your O2 sensors. When the O2...

A lot of people over here in OZ are disappointed with Ford Australia. On a Holden forum and concern is being expressed about how long our affordable RWD V8 Commodore will last. Their management of...

Got me thinking so I checked out e-bay. Is this what you were thinking of? (Last time I tried linking I got hit with the auto spam bat so here goes nothing...)
