hmm ive seen on the site a blitz ecu running tdo4s on a 1.3 hmmmm
might be ok running a ct9 on it so,i might give it a go and put it on a rr to see how it fairs out
this is exactly the thing that brings us back to the argument of how other parts of the world are able to acheive really good results without engine failures which seem to be common over there with similar set ups.
just because a blitz ecu seemed to run on ok on a 4e with a tdo4l and more boost or what ever doesnt mean that it will be ok on a 5e with a smaller turbo.
5e is higher compression even with shaved pistons they are still 9.0-9.1 static compression. which means they are more prone to detonation as the internal pressures are higher and the combustion temps will also be higher to match. with a pre mapped ecu such as blitz or jam etc they would have been tuned to that specific set up that the car had at the time of installation. so putting it in another car with a different engine and turbo may seem to gain better power results because it has allot more advanced timing map than the stock ecu but who knows what the ignition timing map is actually doing, how high is it going at WOT etc. this is crucial on a higher compression turbo engine compared to a lower compression turbo engine which can handle more pre combustion without to much problem.
checking the afr is a good start but it wont mean that your engine is guarantee to last the distance. it will tell you if the engine is leaning out which is one major cause of piston and ring failure but not the only cause. detonation due to high internal combustion pressures temps and to much timing and the other main ones. and on a 5e you have 2 of those three to begin with before you go and out a tricked out ecu on it that you have no idea about what its telling your engine to do.
retarding the base timing 2-5degrees will help some, but wont stop anything from happening if the timing map on the blitz ecu is way too high or off in the wrong place.
my engine has lasted the distance because i checked and adjusted the afr, and backed off the timing on the stock ecu (worse timing map than 4efte ecu) and have only run low boost (8psi) except for when i had boost control issues when it was at 14 but i wasnt comfortable running that much boost without an aftermarket ecu. which i now have and will be installing in the next few weeks.
good luck with the build, good results can be had from such a simple set up but just take it easy and be careful. done leave anything to chance as it will come back to bite you in the ass
cheers
