Thread: S4 + JWT ECU (or Calum) anyone run this?

I used the same program. I was N/A with S4 cams, 370cc injectors. It had the turbo program but i ran it n/a. It was fine ran perfect. I dont have a wideband yet so i dont know my a/f reading.

edit, you can run S4's without a reflashed ecu. I did for about a year.

This is probably because JWT has their own program for JWT S4 cams. I'd imagine JWT considers that program to be their intellectual property. Calum doesn't want to go down that road.

I'd just get a Calum real-time if I were you. Cheaper than a JWT and you can mess around on the dyno. It will probably not lose value out there in Czech Republic.

I have a program for S4 cams from one member who ran same engine/mods. He tuned his car on dyno, so i hope its ok.. and ive sent my ECU to Calum about week ago => waiting.

So your work paid off. Glad you got what you were after.

Hehe, yeah. Im glad too, thanks.

sweet all you need is a basic board anyway unless your really into tuning. otherwise you can just burn new programs one at a time or have someone with a real time tune your car and put the tune on your chips cough(setzer)cough.

Ive got one bin for 10:1 DE, S4 cams, header, intake, exhaust,...

here is the AFR, what you think guys? Is it safe?

That a/f graph looks terrible.
