with the boost soleniod, what settings do you use? it is like a normal EBC with set/gain/etc or are there other settings? also, how does the boost controller interact with the MAFTpro? (like, does it self adjust based on certain aspects?)

i read the install website you put up cobra, but am a little lost with the wideband part. i will probably ask more detailed questions when/if i buy this item, but what type of wideband sesor is required? i know you can buy a bosch sensor for $79 without any of the electronics that accompany it.. would this work for this application? also, is there a wideband readout built into the pro? (if i tune via wideband, i will also have a EGT guage so i can see if something goes drastically wrong)

Thanks for the help!

ive done some searching to find out all the info on the boost controller other than setting it. you can only set it vs RPM and TPS correct?
on a normal boost controller, the wastegate remains closed all the time until desired boost is hit, correct? why would you want to wait till a certain rpm to enable the boost system?

is there any major advantage to using the boost controller that comes with this system over my current boost controller (profec b spec2)? such as the maftpro adjusting boost based on A/F or o2's or anything similar?

Also, can you plug This Wideband O2 directly up to the maftpro without purchasing anything else?

another question that isnt as important, but i would like to learn more about... which knock deterant system would work the best in conjuction with maftpro? (propane, meth/water, alchohol)

Thanks for the help!

The boost control feature works like most boost controllers, with a boost setpoint, gain, tps thresholds, spool features, etc. You set the target pressure and tune the gain a little and you're there.

For the wideband, you need a wideband controller like a LC-1, PLX, LM-1, etc.

I use this one: Wideband

It wires in really easily, works great. The Pro can display the wideband reading on its LCD, and you can log it on a laptop.

If I connect the white (+) wire to the MAFTPro input do I need to run the ground wire from the wideband ground in MAFTPro to the ground for the M300 or can I just connect that white wire to the MAFT Pro input.

Also, how is the wiring diagram for the 98-99s coming along. I think I have it figured out but I want to double check my work.

You would connect the wideband ground (purple wire, 10 pin connector) to the PLX ground, wither at the PLX(best) or wherever the PLX is grounded.

I will do the 98-99 diagram today.

The RPM threshold is there to keep the solenoid off until you need it. Since you can hear it buzz, it makes sense to delay it slightly. You can always set it to enable really early.

The solenoid stays energized (preventing the boost from getting to the wastegate) until the boost is above the "Start Psi" which you can set. This way if your boost tends to overshoot, you can have the Pro turn off 'spool mode' earlier.

The Boost is currently independent of A/F or other stuff. If it makes sense to link the functions we can certainly do that. A future release of the Pro software will have overboost protection which the aftermarket controllers can't do (AFAIK). By integrating the boost control into the Pro, it saves you money.... and you can log the boost control paramters along with the other stuff to the laptop.

I like alky injection, I usually use denatured alky from Home Depot, works great.

See my previous post about the wideband, but you can't just plug a sensor into the unit.

Can I ground the entire PLX then through the purple wire (disconnect the unit from where I have it grounded now and connect it to the purple wire? Thanks again Bob.

I appreciate all the help you are giving us.

No, the purple wire is used to sense ground, not be ground.

So then I should tap the current PLX ground with the purple wire?

[TurboBob]

yes, that will work fine.

(many thanks to Jeff L, as I gathered some of this info from his site)

Thanks Bob. That matched exactly what I had.
