Re: 2T Tank Suggestions

In response to the OP - you definitely need the full washer bottle if you use the car day to day or you will be forever filling it up. One route popular with DIYers (myself included) is to use an actual 2T tank, from a moped or similar. As a bonus these are often fitted with a level sender too, for ...

There is a Sohn thread somewhere where folk have uploaded their solutions.
I think it fell off the forum a while ago :( it's a shame as it had amassed a good selection of different approaches. Perhaps we should start another and sticky it :-k

Re: Hayward project N/A power Target 280+ HP

Idle is best adjusted by altering the target idle tables. There are several for different conditions so it's more than likely just a case of raising the lowest values if it's stalling when dropping to 790/810. If you prop the throttle pedal I would expect the PCM to eventually ignore its input if yo...

Just for comparison, I pay a local guy just under £50 to do mine. This includes evac, fill with nitrogen and dye for leak test, another evac and then re-gas with lubricant.

Re: reducing air intake temps

That's the stuff. It works very well as the bedroom I fitted it in (mine) is now an oven at night (it stops the heat getting out #-o)
Also, fitted between studwork and the plasterboard it makes using drywall screws a nightmare, as the insulation bunches and wraps around the screw #-o #-o

Re: reducing air intake temps

I think the elevated intake temperatures are not for want of a more direct path for the intake air, but rather heat soak in the air cleaner assembly and pipework itself. The filter box and MAF sensor tube can get quite toasty, and at idle/cruising RPMs the air is passing through slowly enough to bec...

Re: Cleaning grease near battery connectors

They are pretty well shielded from the weather and don't tend to corrode. If you do want to use grease I suggest cleaning it all off first and re-applying after you have connected and tightened the terminals, but you shouldn't really need to these days.

Re: Fitting an exhaust manifold

This is the problem with some aftermarket units. The standard cat is a beast - to go aftermarket you need something very chunky to cope with the output. Something that would be more at home behind a serious turbo four pot or a V8 perhaps. Let us know how the bigger one copes!

Re: Fitting an exhaust manifold

:whathesaid: A table for enrichment decay was uncovered in ME ages ago but exactly as Pete says, it's function is not simply to warm up the cat so it's best left alone.

It's basically the equivalent of one of these:

Re: Fitting an exhaust manifold

The core will be saturated until the enrichment decay is over after cold start, but it does then recover. I deleted mine years ago and the original cat still aces the emissions test (approaching 90k miles now), but as ever it's an 'at your own risk' affair. It's worth remembering the PCM does run th...

What fo you do about the air pump for Mainfold delete it or put it back on ?

You can delete it (I have), but you will need someone with MazdaEdit to disable the CEL for it or you will be resetting your fault codes every other cold start

Re: Methonal injection

It would allow you to advance the ignition timing for more output however tuning the PCM for this could be tricky depending on the system you have. The benefits are outweighed by the cost and effort rather than the weight of the kit, for an NA setup.

Re: Circuit test solenoid

This is for disconnecting the coolant feed and return hoses from the throttle body and is a little overkill to be honest. You can leave these connected and just move the throttle body aside, or alternatively I simply tie the hose ends above the level of the expansion tank after disconnecting. Either...

It does pull out but there is a locking tab - air_solenoid_valve.jpg This makes it essentially impossible without removing the UIM first.

Re: Circuit test solenoid

The air control valve is relatively robust, and it sounds like you have witnessed the pump working. If you're getting a p2259 then the solenoid valve is probably the root cause - I would whip it off and test or just replace it. They do get weak and fail over time and they are not expensive :thumleft:

Re: Circuit test solenoid

The PCM does test the electrical side of the solenoid for you and will light the CEL if it finds an issue. You are correct in that it only receives power during SAI operation, which is usually after leaving the car cool for several hours - overnight will cause operation on next start. To test it man...

Re: Priming Oil system

Total capacity is 6.7L - with about 2L in the coolers and lines. I would now turn it over for ten seconds with the accelerator fully depressed (to prevent starting) then check the level again. It will likely need another litre before you fire it up :thumleft:
