Added new EGT sensors.

Well Christmas was good. Santa well (Me) in this case purchase this.

Now I have a Hybrid Ecu Links and Haltech setup. Need this Can Amplifier to make the EGT sensors work.
 
I have the car in a run in tune at this time, 4000rpm limit. Full race tune Jan 21. Mikey test drove the car and it impressed him, that's hard to do. So the build is as planned. A 250 to 300 rwkw and up to 450mn of torgue, and by 3000rpm 12 - 15 psi boost.
 
 

Changed my mind I have added new spool rod's.

Well it has a tune
Green line on waste gate spring only low boost
Red line 18psi high boost.
This is a very safe tune.
This car has far more power to go if i want. Will look at a more after putting 5000kms on the motor.
To get this extra power we will tune higher boost leaner afr, tune each cylinder and adjust cams gear to see what the motor likes.
This power has work out just how I wanted it. Heaps of mid range torque. If I want more above 6000rpm I will change exshaust housing from .64 to .82. at this stage I love it just the way it is.
I let Mike drive it he replied saying "this is the fastest 3-sgte mr2 he has driven the response is excellent and it does not need any more power." It's hard to impress him.
The tuner thinks with the current setup power could be acheived between 250 to 280 rwkw will be the target when I bring it back.

You don't need EGT sensors to have a safe tune.
It sounds like you need to find a new tuner.

My point is that he tuned your engine too close to the edge. Good tunes have a little bit more fuel and a bit less timing to what will give the maximum power to have headroom for error.
I'd rather make 5% less power than have a blown up engine that made more power. 😊
The flow differences between runners on that manifold is well known and should have been added to the tune.
I have that included in my GT4 tune. I have a little bit more fuel in 2,3 and a bit less in 1,4.
If your engine had a safe tune, it wouldn't have detonated.
EGTs are your last line of defence so you can use with engine protection. EGTs are not your first line of defence against detonation.

Yeah. It sucks that this happened.
I had an engine melt the tops of two spark plugs a few years ago. The bits of metal then got stuck in the value seats causing loss of compression. I had to rebuild the engine, as the pistons and bores were also damaged.
I then changed to a different tuner and haven't had an issue since. My current engine makes good power and has been very reliable for years!
I go to Croydon Racing Developments for my tunes. They are a bit too far away for you though!
