I changed the timing of my single turbo FD3S , I have an AEM ECU , but I'm a litle lost with the timming , I have take off a lot of timming but think that the EGT are too hi cause the turbo get too red at WOT , and I don't know how to tune the split ignition map , for the trailing. Im running extra rich , like 10 or 10,5 A/F

The engine is street ported with a T04e turbo.

Please help me out with this problem.

I know that if I take off some timming the EGT should get down , but I don't know how much I have to take off.

And I don't know if I have to split more the trailing map at full boost or I if have to split less.

Please I have been working in this car for the last 6 years so ,this is the only thing that if left.

 

Try the forum for your ecm system they may be able to walk you thourgh the process a little easier. Did you log your temps and timing before and after the conversion?

 

nop , cause when I started the project , the car was compleatly standar, and the engine was with a water seal broke, but I use to have another RX-7 single turbo , I mean with that turbo , ut with a Pettit Racing ECU , and it works perfect , and without that EGT. In case the other car was with a 100% standar engine

 

I have a conversation with my engine builder and he give me the direcctions for tune ir properly , so I just need to know how can I check if the ECU timming is rigth?
