I found a recommendation for this forum in a thread from 2006 (!?) in a Swedish trackday-car-forum and from the discussions you have, it seems to be the right place to sort out questions regarding ECU/chip v.s. various engine builds.
I am helping a friend who is fitting a G13B engine (BBBBC block) into an Austin Mini -75. The engine has unknown history and needs a full overhaul. Nothing is broken, but the cylinders needs a hone. So, from just a restoration, we are now at the point where wilder cams are "approved" and a set of JE 11.5:1 pistons will be fitted if we can sort out the mapping. The engine bay is microscopic on this car, so we probably stick to stock exhaust manifold. Moreover, the car will be used as a fun street car, passing emission tests, which limits how crazy we can be.
Now the issue is that we don't find anyone providing tuning chips or knowing theses ECU's here in Sweden. The best option is the moderately priced chip from theses guys: http://www.turbonoz.co.uk/suzuki-chips/TNTCHP00109.html
However, it seems to be optimized for the standard 10:1 pistons.
So, to the questions:
- CAT Cams have a great selection of cams. Comments? Recommendations?
- Any other cams, you can recommend?
- Can you recommend/provide a suitable chip tune for 11.5:1 CR pistons and a slightly upgraded cam?
- Or, is an aftermarket piggyback, or standalone ECU the way to go (prefer not to, due to budget)
- Alternatively, do you know if/where the ECU addresses are available? (I can write EEPROM's)
- How high should we dare to rev the engine? 9000 rpm?
- Have we missed any obvious components to pay attention to for easy gains in performance?
- Or for reliability?
From what I understand the crankshaft and the connecting rods can stand 9000 rpm, the injectors have capacity for 150+ hp, the clutch will handle this modification.
