after starting several other threads and taking advice, reading through the megamanual im still not getting anywhere

iv got a new map from diy autotune and calibrated all my sensors.

warm up enricment is perminatly on and will not go off at 71 when its sposed too.

my ideal is pretty horrid

and as i go along or hold revs it cuts out for a second or so.

i realy have no idea,

would you mind taking alook at my msq and a datalog i have attched

thanks

I don't think you needed to start another thread, you were getting help in the old one... Just hang in there, keep listening and reading. Eventually it will click, and hopefully you won't blow anything up until that happens.

i have read everything, i have learnt alot but its not helping me get anywhere

can you give me any advice? or just tell me what to do

ianferrell

I can't currently, I'm at work. What I'm saying is you may have to re-read, stuff that didn't make sense the first time that you probably glossed over, will make more sense on subsequent passes. I spent about 3 months reading about megasquirt before I had my first car running on it, while that was different in that I was building a harness from scratch and working with an unknown platform (sbf v8 rx7 with a 'semi-built' motor)... I assure you that once you understand that concepts, and figure out how to trouble shoot individual problems it becomes very easy.
Hell, when I built the diypnp for my brothers car and used diyAutotunes basemaps... damn thing fired the first time we turned the key... So much easier than working from scratch.... all of your questions have been answered, you just have to search. If at first your search doesn't succeed, re-word it till you find it. There are hundreds if not a few thousand megasquirted, turbo miatas out there, someone else has had whatever problems you're having already, and they posted about it on this site.

this has been ongoing for several weeks now, and all i seem to get is just do a search and read up on it.

i have search and i have read...and oh look im in a worse place than i was when i started.

if your not goign to give me some direct advice regarding helping my set up then dont bother posting please

my money is on: you either have an input source (afm, tps, temp sensor, cas, o2 sensor, etc.) or an output receiver (injectors, coils, solenoid) which isnt functioning correctly. Find and fix the malfunction. May be something as simple as "Oh, I forgot to reconnect the ECU temp sender", or something as unfortunate as "Well ****, guess I F-ed up the wiring on the CAS"

AND DON'T START ANOTHER THREAD ON THIS SAME PROBLEM.

Why?
Because now, If I want to get background info on the problem, I have to FIND YOUR OTHER THREAD to see what the hell you've already done, and what advice you've already been given. I'm lazy, and helping your car run right isn't going to improve my life; therefore, there is no motivation for me to search, find, and compare your multiple random threads (what are you up to now? three?) on this topic.

Just like what Matt said last time you posted. Your fuel table is a mess man. It might be a really good idea to visit a professional tuner for a dyno tune.

Your over run settings are also pretty agressive. I'd turn it off for now.

You also need to disable the secondary fuel load.

Viper

ok

how do i disable the secondary fuel load and the over run settings please

thanks for the advice

Matt Cramer

Basic Setup -> More Engine Constants, set Secondary Fuel Load to Disabled. Why did you enable it?

Extended -> Over Run Fuel Cut, set to Off.

hi guys,

after all that work it seemed i had started with the wrong base map in the first place.

i managed to go out today with the right one and got it running again, i even managed to get over the 65545rpm issue by searchign and reading as i was told to do so.

but know im a little puzzled as my fueling seems to be okish, i know it needs more work but i cant explain why the car idles very badly and runs horribly, is it possible its not the map but maybe a missfire?

iv attached the new msq

please heve a look see and let me here you opinions
