I was thinking of making a fiberglass radio bezel and setting it in there recessed. using velcro.

I want to replace my stereo with a single DIN, and put the factory DIN pocket in the bottom slot (or top slot...). Then I can cut harness holes in the back of the pocket and keep the Pro in there....

Of course, I haven't measured it......

i was gonna do this but its slightly too wide, although im using an aftermarket CD holding pocket underneath my single din stereo, so it might work with the stocker

For the decel stuff, watch the STFT (short term fuel trim) and see if its lean, also let me know what the LTFTs are doing.

On the high RPM stuff, where are you "adding fuel"? (which setting) What are your trims doing when this happens?

Bob

I was adding fuel in the low throttle ranges for my high RPMs because the car was still in vacuum (either very light accell or trying to cruise).

Technically if the VE table is close, shouldn't most of the settings be 0 on the tables if we want the car to run like stock as long as the global gain is adjusted for bigger injectors? I have 15% added in at 4600 rpm and it still goes super lean (reads lean on my M300).

TurboBob · 09-19-2005, 06:02 AM

You are right, and I believe the VE table is pretty good. I think the ECU may be entering a decel enleanment mode which is why I asked about your trim values when it happens. If your short term trim 'freezes' then its a sign that the ECU has changed modes.

I was thinking the exact same thing cause my indash 5 cd changer is broke, stupid thing won't give me my cds back either

How do I get around this if this is the case. I am at work now and won't be near the car for a while but would like some ideas to try.

Bob

well if this is true, would raising TPS 1 alleviate the problem?

TurboBob · 09-19-2005, 11:34 AM

TPS1 is only when you tip-in.

The Pro only has one output, and that's airflow. So richening that range so the ECU doesn't enter decel mode is the way to fix it. I believe its an airflow/RPM threshold combined with very light throttle.

Is there a noticable glitch in driveability, or does it just go lean at these times?

The system has a ton of adjustability and that spot may be lean in the VE table.

Grab some trim info and post or PM back and we'll dial it in.
