lc-1 and MAP user error
 

I moved my vac hose to the FPR port, and I've tried every combonation of grounding arrangements to stop th noise and innacurate readings on my 1.6. I'm at a loss on both. I plan on buying a ricer grounding kit for the next step.

what exactly is your perceived problem?

is my afr datalog too spikey? Most of the ones I've seen are nice and smooth. Does my AFR log look fine?

Looks fine to me. Make sure you set up MLV correctly for 0-5V = 10-20:1 not 7.35-22:1

its set up this way on both outputs and running the linear 0-5:10-20 in the configurator.


and I still can't get autotune to work.

should I set up any delay in the lc-1 to smooth that out?

You have to set it up in MLV too. Autotune sucks. Don't use it.

+1. attempted to use it when it came out on my probe, fail

I did all that according to the thread and it constantly says "out of range" or whatever. the VE analyzer makes my fuel maps absurdly out of tune...at the 100kpa spot it will do shit like 88, 40, 12, 80, 55, 55, 12 accross the rpm range at 100kpa. I just started tuning manually and got everything close...if the WB is reading correctly.

I'm also getting weird software shit where megatune randomly closes.


I really want to get this shit worked out before I drop in the high dollar motor and put down some positive manifold pressure.

That's a funny arguement. Before my injector swap autotune worked beautifully. I had a perfectly tuned fuel map with EGO turned off. It was beautiful.
Then i did something on the computer and autotune doesn't work worth a damn. Neither does MLV. For some reason MLV make my fuel map 2-3 AFR too lean across the board. Rendering the car 100% undrivable.
When i get home i should spend some time on msefi talking to the developer to figure out my issues.

high load should be tuned on a dyno, not with any type of autotune. veanalyzer should knock out your cruise tune stuff fast. but it doesn't look like your wb is config'd in MLV correctly.

I've never seen autotune work. I know you can edit the program to make it a bit more accommodating, but I've never needed to. Make sure your WB is config'd correctly in MLV. It's a separate program from MT, hence has its own set up procedure.

what is there to do other than set it for "innovate 0-5v"? Why can't I tune fuel at high load on the street with a conservative spark map?

no, that's it. your min and max values on the chart show 7.35-22, so I thought you had the default values plugged in there. :dunno: rock on with your bad self.

you want to tune the high load stuff by hand on a dyno. i wouldn't trust the computer to do it. though it might work out fine for a low power NA car.

oh shit, I opened the log on my desktop with the default lc1, not the notebook with the correct config. I plan on getting a solid road tune for break in at low boost on the street, then promptly driving to the dyno for assrape prices on tuning.
