Does anyone else's turbo pop and bang? I've got a 3" system and it still doesn't pop, does anyone know if it needs to be mapped in? Cheers in advance Johnny

[chickendippers]

Mine did some lovely bangs and flames. Any established Vauxhall mapper should be able to add it to your map with ease, RnD Motorsport, SM Tuning, Rabbid Remaps etc 😊

Send a PM to siztenboots he can help with your mapping.

Means it's more economical and quieter and your exhaust stuffing will likely survive better. Also it won't scare people when you over take them.

Plus the EGT is lower. If you want pops and bangs you better throw fireworks out of the window while driving to get the attention of passengers and cops. If you really want to risk the engine and turbo: Just set the timing advance to 0 at throttle closed, deactivate the decel Fuel cut and then fry your valves, Turbo, cat, O2 sensor and exhaust stuffing.

Mine started popping at stage 3. Just every now and then in 3rd gear it makes the most unbelievable bang 💥 😛. Childish but fun...

Stage 2 decat pops on track and gives some flames but by no means gives the effect of an ak47 on overrun, which I assume you are looking for

Mine gives lift off burbles and bangs on demand with ease, very predictably and manageable on the throttle. Courtenay stage 2 map with Larini, precat delete, and sports cat.

you just need to set the minimum ignition timing map to -10 degrees ( or less for very severe lift off bangs ) , for the first two rows of low load and across all the rpm range.

 

this will then pop bang on over run lift off and if you then lightly touch the throttle to put fuel back will give that blub-blub-blub noise

Mine seems to do it more when cold - does that make sense?

[VXT Tim]

Mine does it only when warm and only when I change from 1st to 2nd under specific boosting circumstances but the bang is absolutely deafening.

Pour water on the coil pack, mine always starts to pop and bang when it's on it's way out.

Ecu adds a little bit more fuel when engine coolant is cold , similar to the old choke , fuel enrichment.

[scw02102]

mine didn't do much even with both cats removed until I had it mapped in

 

just get a mapper to do it and it will pop and bang as much as you like

[siztenboots]

So an update, Johnny popped over to the office and we updated the existing map and he had a couple of drives before we got to the desired level of acoustics that worked with his exhaust setup. Having demonstrated how extensive the TeamVXRacing software is , he will soon be back for a 260pack.

You can get that with a p*ss poor map.. normally the sound of Engine failure lol
