I went to the dealer today.

What a shitty dealership. I get in and they've lost my appointment, so I pull it up to the service front desk. The guy there asks me "is there anything wrong with the car?" I tell him to check coils, cat, plugs, wires, and compression, just like I had stated when I made the appointment.

He ended up checking nothing.

He told me I needed to come back friday to get the coils/plugs checked, and that he's charging me 400 dollars for it.

No. That's horseshit.

I didn't argue at the time, I just took the sheet. He couldn't stop telling me "I doubts its the coils. I doubt its the plugs. If you just listen to it in the back...the plugs are fine."

Not to mention he wouldn't let me back into the tech area to see what they were doing.

They gave me MSP-16 which in terms of feeling power did absolutely nothing. I didn't really see what it was going to do that the AP hadn't already done.

They told me to bring it back next Friday.

Compression test is included in the 400 dollars.

I will update this thread next Friday.

Might be somewhat late to the party as I've been away a few days, but they will, or should..................give you a loaner car.

I knew that MSP-16 wouldn't do anything before I got it, because if the Accesport messed with the same settings and its proven, refined map can't save the power, not much else out there will.

I have just dropped the car off with another dealer, who was visibly distressed by my numbers.

He says there has to be something wrong with it. He's checking compression first and if that's fine, all the other usual stuff.

Will update as I'm updated.

I just got a call from the dealership.

Amazingly, the compression on this motor is 8.9 average on both rotors.

The dyno doesn't show the typical bad coils signs, so that leaves me with plugs and cat. I told him check the plugs first and cat if all else fails. Once I get it back I'm going to take it to the dyno and see if it has improved.

I'm going to test it once without the AP and than three times with the AP, and I will post all graphs.

I have the compression sheet and will scan it tomorrow.

I will be heading back to the exact same dyno hopefully this weekend, to get a re-test. It definitely feels smoother and the tach no longer does stop-and-go above 7kRPM.

I don't know if I gained 30hp, but it DOES rev more smoothly.

I will be posting before/after AP dynoes as well for anyone who is interested.

What changes were made? I realize you had a compression test done but what else did the dealer do? Did they change the coils, plugs, wires, or cat?

This is the compression test I had done first at the dealership. I figured if the compression was low that it ruled out some of the other problems. I don't really know how to read what it means, so I'm posting it here, attached in PDF.

After that, the coils were checked, they were good. The plugs were "slightly fouled". The cat is "good".

I know that 9.0...something is great compression, and 7.0....something is bad compression. I do not know if this sheet reads in the same units of measurement.

I don't know if anything is fixed. At this point I don't think that I feel 30hp faster.

Uh, little problem there with your "compression test".
890 kPa isn't 120 PSI. It also isn't 125 PSI.
It also isn't 8.9 kg/cm^2.

This is a bogus test. The numbers were inputted manually by someone.

^^ yep.

Math is wrong, something is wrong

For exmaple. 125 psi is about 861 kPa. not 890

Ask them.

For example, here are the numbers from my "old" motor at 215 RPM:

FRONT:

768 kpa - 111 PSI - 7.8 kg/cm3
779 kpa - 113 PSI - 7.9 kg/cm3
848 kpa - 123 PSI - 8.6 kg/cm3

REAR:

825 kpa - 119 PSI - 8.4 kg/cm3
825 kpa - 119 PSI - 8.4 kg/cm3
779 kpa - 113 PSI - 7.9 kg/cm3

I'm on hold with them now.

EDIT: He told me "He'd look into it" and that "he doesnt have conversions in his head", that he "really didnt have time right now" and that "I should call back later or maybe tomorrow and he might have answers." He also said "the numbers come right out of the mazda computer and that its smarter than all of us put together" and that "he doesn't know how to change what comes out of the computer."

This isn't looking too good right now.

AFAIK:
If they have the digital compression tester Mazda makes the licensed dealerships use, it should be a screenshot of the application view. It also sends it directly to mazda upon completion.

That screenshot is not that program.

Considering that it is an absolutely base-model laptop, that is saying loads about the intelligence level of the dealer service writer.

I just talked to the dealer again.

What he told me was "the middle [numbers] are all we look at. If the other ones are incorrect it might be because we don't...look at those. We get one reading from the compression tester which is in kgf/cm2 and than we just input those into the computer and it generates the other values. The other numbers...we don't look at those."

I didn't know what to say about that so I told him I would call back. What do I do? They are obviously bullshitting me but I have no way to call them on it!
