2011 Great Wall Hover H5, TAP-01

[golubsasa]

Good day,

I have Great wall Hover H5, year of manufacture 2011, 4G69S4N engine code, petrol od 2,4 litre.
Of course powered by LPG, STAG QBox Next plus and TAP-01.

I need help and advice how to tune TAP-01. Right now is set with +9 degrees value in range 1000-4000 RPM. In range 4000+ value is set to 0, since that was a recommendation from Russian Great Wall forum.

But, when going uphill on LPG I hear valves knocking.

Can you please tell what is proper way for adjusting TAP-01, or maybe you can send me directly file to insert in TAP controller?

Best regards and keep on doing great job!

Hello

9 degrees is way to far ...

Use max 6`degrees just over the idel rpm lower it down to 3 arund max rpm.

For IDLE keep close to 0 degree, for middle load 2-4 degree, for max load 6-9 degree. This is calculated as 20 to 30% of the actual ignition angle.

Thank you, I did as you both said. I started with +3 degrees at low rpm, than up to +6 degrees at 3500 rpm, and than down to +3 at 4200 rpm.

Tell me please, what could be consequnces of bad spark ignition timings?

Is it maybe, more appropriate (reliable) way to leave, for instance +2 degrees in entire rpm range 1200-4200 rpm?

Too long ignition timing will reduce engine power. it can also cause greater heating of the cylinder walls. You can set +3 degrees on full range rpm.
