Safe to drive on base map for "lite" shakedown?
 

i've got the basemap from diyautotune on ms2 on a 1.6 turbo and need to get the car about 30 miles to my house and was just looking for some advice before i make the journey. i'm going to do it early sunday morning so i dont have to deal with traffic and such.

these are the steps i've done to ensure a relatively safe trip;

plugs are 1 step colder and gapped to 32
injector size is plugged into ecu
car idles a little high(1,000) but doesn't fluctuate or have any issue starting
1-20mph afr is between 13-15 (just driving around the block)
no oil, coolant, or piping leaks
timing checked and is at 10 both on crank and in megasquirt
will NOT go more than 1/4 throttle and will stay in right lane and monitor gauges (oil pres and temp, boost and afr, wat temp)
my AAA premier membership card handy...

you guys think i'll be good to go?

You'll be fine,just stay out of boost. Can you not tune it while you drive? You could just autotune while you drive and get the afrs closer to where they need to be.

i'm still figuring out how to connect the AEM wideband to megasquirt. i dont really understand the instructions. can you shed some light on this? i have ms2pnp and aem uego

Easy peasy! Should be a white wire coming off the aem uego, just need to figure out what wire is for the wideband on your ms2pnp.


"The MSPNP2 supports many common wideband oxygen sensor systems, including the Innovate Motorsports LC-1 and MTX-L products, the Zietronix ZT-2 and ZT-3 (among others), and most other systems that provide a programmable analog voltage output. You will need to install the controller according to the manufacturer's directions and then connect the MSPNP2 to a programmable analog output from the wideband sensor's controller. You should ground the wideband to the engine block near the factory ECU ground wire to ensure an accurate reading.

There are two ways of connecting the controller to the MSPNP2. You can either connect the analog output to the pin labeled Oxygen Sensor input of the option connector, or you can cut and splice the oxygen sensor signal wire to the analog output. If you use this pin for wideband input, you must disconnect the stock oxygen sensor. Do not ground the oxygen sensor wire if you disconnect it; leave it completely unconnected and taped off if necessary (make sure it can't short to ground or anything else).

Looks like the wiring coming from pin 21, 3rd from the right on the bottom row.

Personal I wouldn't without the wideband

Definitely this, I was under the assumption the wideband was good to go by saying "1-20mph afr is between 13-15 (just driving around the block)"

Wideband is super important to know whats going on.

ah ok, easy enough. i dont have the unit in front of me so i had to look it up really quick. how do i connect this? should I solder a wire from the white wire and then use the pins they included or just stick the wire straight into pin 21?

its plugged in and working, just not connected to MS

Yes, use what they have included.

thanks so much, really appreciate the help.

The way I installed my wideband was to delete the factory O2, wire the signal output from the gauge to the stock signal in wire from the stock O2. I left it at the P00 setting so it is a 0-5v signal sent to the ecu. Then I calibrated the values in TS.

hey just a quick update. i have my wideband successfuly synced up with the ecu and they are on the same page when they show values. anyways i paid for the upgraded tunerstudio so i can autotune on my way home just to be safe. any last words before tomorrow morning? lol

Dont blow anything up...

As long as afr is un the 11-15.5ish range you'll be fine driving it. Dont let it go to 17+. Use autotune and it will keep afr in check.

Baby the throttle.

Super paranoia mode would be wire the waste gate open... Doubt you need too though.
