13.5v while running

 

Few things for you to check-

• Are you setup for sequential fuel? i see not under general but under injector drivers i see "additional"
• barometric correction is set to off and you default to 100. Have you tried changing it to initial and unchecking the box on "default"?
  • may want to try "incorporate afrs" unless your ve table is rock solid
• Idle- I would start with Open loop. Also the valve frequency is really high.Try around 170hz and I think you are around 480

Not sure if that's what the base map gives you but certainly something I havent seen before...

Also you should be able to start a data log, crank it and if it dies thats ok. Start it again and if it dies again you can turn it off and post it

 

Thank you for the input. It is VERY much appreciated! I tried the things you suggested. No, car is not setup for sequential but oddly was the only way it idled for awhile yesterday. Put the settings back, and changed what you have suggested. I am going to attached my current MSQ (which started with the 9093 base tune), then just added. I took a datalog for a min or so without map line connected (rich), and also for like 10 sec with it connected barely running (lean). I hope they have enough information in them to find where im messing up. Thanks!
Shows 77 kpa with car off.

 

What wideband and did you calibrate it?

Is your tps stock and disconnected or are you using a 1.8?

 

Have an Aem uego wideband. Have to enter values according to aem instructions because it isn't an option. Car is a 92 with stock 1.6. Have the tps disconnected

 

I'll check in the am. I know those settings settings so that's not a problem.

Stay tuned

 

Thanks so much. Look forward to it

 

The values in the AEM instructions weren't even close for me, or for anyone else here.

Have you checked that the AFR shown in TS matches your gauge?

 

Go unplug the sensor on the wideband and compare the gauge and the tunerstudio dash. Do you have the same value of 14.7?

Looking at that second log - sans line- it is lean as hell! Have you checked fuel pressure?

 

It is about .5 - .7 difference. TS being higher

 

They are about .5 off from each other. When should it read 14.7, with engine off, ign on?
And checked fuel pressure through TS?
Yes, it is super lean with with map line connected. Dont understand why it runs "ok" with it off. Am baffled why my map is reading 77kpa, instead of around 100.

 

What values do you have in there?
0v=10:1
5v=20:1

I suspect it is because your VE number for the 100KPA row is different from 55. Ideally you need to get an accurate reading of KPA

 

For the AEM Wideband?
1.09v=12.8
4.06v=18.1

For the MPXH6400 map sensor
0v=3.5
5v=416.5

 

Slightly off on the aem. Try the ones I suggested and see if it helps get you to 14.7 with the sensor unplugged.

Is that the mapdaddy upgraded sensor? Do you have any pictures of the unit? I know that calibration is right for the map daddy but not sure that's what you have...

 

Wideband reads 14.7 for 30sec or with ign on then goes away.

Sensor is stock to my knowledge, looks stock. Says MPXH6400A on it.

 

As I said, the values AEM gives won't work. There are several threads here discussing it. I'm using 0.35v at 10.0, 5.6v at 18.5.

Looks like the MSPNP2 comes with the 4 bar "map-daddy" sensor standard. That calibration should be correct.

 

You are correct. I had that problem previously but found it to be a grounding issue. As for the sensor- I was not entirely sure which unit it was but that looks correct as well.

Where is that vac line going ? Is it on the throttle body side or towards the back of the motor?

 

Ok, thank you. Will try the different wo2 values.
Now just for the damn map sensor

 

I have the vac line tee'd off fpr/intake mani line. Still reads 77kpa when I have nothing connected to ecu. I don't know what else could cause low kpa reading.

 

Could a software problem cause this? Or voltage problem to ecu? Anything else to check.
