Megasquirt and 50 degrees advance
#1
![Default](https://passionford.com/forum/images/icons/icon1.gif)
Today my tuner came to my city and tried to tune my RST. RST has standard engine. It only has EFI engine. I used MS as ECU. The car is almost good but I have a problem on boosting. We must have set 46-50 degree as the boosting advance. We dont hear knocking sound with professional knocking headphone. But we cant find why it does like it. At 15-20 degrees. we cant get power which the car must give.Manifold is glowing red.
What can cause it?

Karlos, he said he's using a EDIS setup, so I assume he's not trying to decode the 36-1 wheel with megasquirt. So the trigger angle should be set to zero and EDIS mode activated.
You might have stuck to the limp home mode with the EDIS giving static 10 degrees BTDC timing if the MS signal to EDIS is not properly confgured. This would cause loss of power and a glowing manifold, and no detonation at any given advance numbers.

I changed crank sensor and now it is very near to the flywheel. I can control the ignition. There is no problem about connection. But It needs very advance. Very silly numbers are on the boosting advance. Help....

I understood limp-home mode EDIS after searching at internet. But EDIS is controlled by MS. I change degree at map the car is replying. I can change the car's going style by giving advance. I am searching why I need this high advance degrees.
Tuner said valve springs can cause it. I will try it. But it is hard operation. I think easy solution can be ?

Normally it will be because of an error in the offset value for where the timing disk is reading from, like the TDC reference etc.
But as the EDIS unit has its own reference for that and you are (i assume) on standard locations, it sounds like it must be the signal to the EDIS that is wrong.
Unplug the EDIS from the MS and check the timing is at 10 degrees, if it is then the fault is on the MS side, if it isnt then the fault is on the EDIS side.
