DIYPNP map sensor spikes/flutter - problems
 
connection problem solved!

now its time for some new problems :D

my map-sensor is reading sometimes peakes/flutters. especially with the acceleration enrichment table (disabled it now).

~2200-3000 rpm its reading +/- 200 kpa/s while just holding throttle (no acceleration - while driving - or just in neutral).

on boost - theres flutter too +/- 150 - 200kpa.

will upload my MSQ and my log later.

post your msq. you probably fubared a setting or possible fubared the firmware.

decided to try a reboot with the boot jumper and a new firmware tomorrow... x

spidy 06-28-2015 01:37 PM

where's your MAP sensor plugged in?

spidy 07-02-2015 10:14 AM

at the rear port at my manifold (the one you can see near the CAS)

maybe the problem caused by my hose adapter? the DIYPNP got a 3mm hose fitted at the map sensor - the manifold got a 5mm hose. fitted with an hose-adapter

thats actually the absolute worst place to put it.

the TB is the second worst.



tee it off the FPR.

spidy 07-02-2015 02:56 PM

ok thx - iīll try that.

at my nissans the after TB slots works fine.

thx for help :-)
and sorry for my bad english :/

so its better - but still on WOT some points with AE and decelaration :/ sometimes with lean spikes

changed ignition cables -> new magnecore (red) and the pressure hose tee of the FPR port.

maybe other problems? VE and ignition maps crappy?


edit: turned my AE way higher - 0,8ms @ 350kp/s is the first point

deezums 07-12-2015 12:09 PM

I don't see a problem, other than crappy tuning. I'd never settle for a VE map that rough, especially near low map and idle. I can't imagine why it has lean or rich spikes with adjacent cells more than 50% out from each other.

spidy 07-12-2015 05:55 PM

too much autotune at low kpa-cells :/ need to smooth this cells and finetune the AE :/
