Do you have "Lambda" enabled in your Project Properties ?

Vanhoe · Post by **Vanhoe** » Sat Sep 17, 2016 12:23 pm

Yes, but it is in Volts, can you change this for AFR?

I can change them now lowere than 5 Volt

2.994 = 14.7 afr

I'm afraid I've destroid the sensor, it won't change from 3.04 Volt even after cleaning it and the thread came out when loosing it to!

new weld bung and sensor

It was the lambda controller that stopped working, feeling verry hot.
With new controller ok again.

When I applay the throttle only a smal amount in neutral MS 1 doesn't see the throttle moving and therefor going verry lean and stalls.

Is this something to do with Accl enrichment, or should / can I use MAP furst and switch to TPS like above 2000 RPM?

I think It wil see the MAP change better going of idle than the TPS movement.

Unless you have a very good reason to use alpha-N, do use speed-density.

I went for an other go this afternoon, already better throttle responce after adding some accl enrichment.
Unfortunally Sparks cutting above 4000 rpm.
Need to datalog this

Is it possible to use Hybrid Alpha_N on a non boosted engine.
I want to use MAP for the lower throttle bins and TPS for the higher ones.

I'm not sure that Hybrid is the way to go as it is more something for adding fuel under boost.

I've Always used TPS and never MAP before , those cars where Always racing applications.

Just use MAP.

James

I'll try it to use only MAP, I can't beleeve that wit MAP once the throttle is more than 50% open it changes mutch in KPa's.
Like I have now with the TPS in the first little movement of the throttle.

Well soon to be experimented!

Thanks

I'm take a guess that over 95% of customers with a standard engine setup like that are using speed-density. What matters is whether the MAP signal is a good estimator of air mass ingested. For a "simple" engine like that with a plenum it usually is.

I bet more like 99% of all installs are SD.

Tune your motor SD as perfect as you can get and then post about a 30 min log with the motor being driven fairly aggressively. It is easy to tell if you really need Alpha-N tuning.

I had the car running fine for 90%, but now suddenly bangs from the exhaust en she wont run smooth
I'ts like the ignition isn't following anymore.
Sometimes when accelerating, missing the ignition and all of a sudden pulls better and how more TPS the worse it gets
When I load an older tune I get a warning :
MSQ units mismatch for RPM4S! 10000RPM/Sec or 70% slip found in current config.....
What is that? never seen before

Can my logs be checked please?

When looging can you higlight a moment when the problem occurs?
Like putting a flag when you feel the problem in the car.
Afterworts you can see in the log where you had the problem and identifie the part in the log where you had the problem.

You can push the space bar while logging and this will leave a mark in the data log. This does not apply to tooth logs. It appears sometimes your ECU is not reading the first tooth after the missing tooth, based on the tooth log.

Vanhoe, your MAP signal has died.

Andy

Vanhoe · Post by **Vanhoe** » Mon Nov 21, 2016 3:47 pm

running it Alpha N, MAP sensor not connected to manifold.
it shows 100 max to 96 min, schould be fine .
Cant seem to find the sync loss parameter in the logs

Vanhoe · Post by **Vanhoe** » Wed Nov 23, 2016 2:30 pm

Placed new spark plugs , again, and she runs fine again!

I think the coldstart is to ritch and the plugs become to wet.
After a few starts the plugs are shot.
