Thanks for the input Lumpy. Thats what worries me. It was suppose to be a conservative tune to.

 

By no means is that conservative. Its overkill. What RPM and load # are you seeing full boost?

 

That im not sure, havent logged or done any pulls after getting the car tune. Dont really want to mess up the motor until i can get it sorted out.

 

too much timing needs about 3-4 degreee less

 

Thanks Evo8vz. it does seem a bit much.

 

If you have a built block then it's ok, why would you ask for a conservative tune when using E85? What type of con rods do you have?

 

E85 doesnt knock
because it feels good doesnt mean its correct

 

So you are aware that E85 doesn't knock yet you're asking him to reduce timing, care to elaborate why? I've been tuning Evos for 11 years now & I'd say that the above table is on the conservative side considering it's E85. My concern, if any, would be the connecting rods, that motor better have good rods & good rod bolts at that boost level x turbo size.

 

Whoa wtf. What does having a built block in this context have anything to do with how you tune an engine?? LOL

Just because the pistons are forged and can withstand a BEATING and ABUSE doesn't mean you need or should ABUSE and BEAT them !!

 

Way too much timing. Go too a different tuner. You shouldn't be seeing 10* unitl like 6000rpm. You have it 4500 where it should be like 2*. You're just beating the rod bearings out of that poor thing.

 

So you would tune both a stock motor & a built motor the same?! Are you a tuner yourself? Or are you even aware of the concept of 'Torque'?

 

You have no business tuning an Evo, or any car really, if you think that timing map is ok.

 

By your logic then it would be negative degrees this if this were a 93oct tune.

 

Umm no. Boost levels would be down compared to E85 so the timing values would be about the same besides up top.

 

These cars have old engines that don't need a lot of timing to run. The only trophy you get for a high timing score is an expensive one.

I've run my car 70+ pulls on the dyno . There isn't a huge change from pump gas to race ethanol for timing with a small turbo/backpressure.

You can just about start off at 2-3* at 3500 and build an easy ramp to 5-8* at 5500 then to 13-15* + on most of these cars. A larger turbo with less back pressure may be able to run more but never get carried away. If you have higher or lower then stock compression that also plays a big role.

The real test is putting it on the dyno and running it back to back to see what timing yields decent results . You don't just keep adding timing to chase small gains. Looking at plugs and smoothness is also a good idea.
