I want to know this because I am thinking of buying a MAP ECU2 and therefore a feeling about when the ECU does pull timing where and when with which octane rating would be a basic for a proper tuning.

Good question, I would also like to know this as I am also debating to go with the MAP ECU 2 or AEM EMS. I would like to reduce the timing the stock ECU gives out at higher boost and be able to run more boost at pump fuel without knock. The MAP ECU2 would be perfect to this, but as you dont know the total ignition advance, it's just guessing, and I dont like that.

I was in the impression that one could only read timing on an OBD-II ECU, but I could be wrong.

I found an article on MKIV.com explaining the different display functions of the Techtom device and there is also apparently the functionality of reading ignition °.
Maybe I am wrong but there must be a way to check IMO...

Pro´s chime in :wavey:

 

The Techtom will read timing.

Where can I get one?

There is no other option that i know of other than the techtom reader to view timing on an OBDI ecu. The re flash rate on OBDI is also very slow compared to OBDII. Your best bet is to convert to OBDII since loggers are abundant.

 

^^^^^^^^^^^^^

Agreed, obd2 conversion+obd2 logger works great for me.

 

Agreed again. Converting to obd2 is better in every way. There is no reason to keep the OBD1 ecu.

 

I just recently asked what the next firmware/software upgrades for the map ecu 2 will be on their forum, and logging of the base timing is supposedly next on the list. They didn't give an idea of when this will be available, but according to PMR, it's going to be made available in the future. I'm hoping that it's sooner than later.

 

You will have to watch the For Sale section, every once in a while one pops up. That's how I got mine and sorry, not ready to sell mine yet either.

 

cant you just use a timing light? i am na-t and maybe its just cause of my dissy but cant you guys still read it with a timing light??

 

How are you going to check the timing under load condition? Wanna place someone under the hood w/ the timing gun and drive around to see if the ECU is pulling timing etc.?
The only thing you can tell maybe is, if the genral idle timing is working when the car is stationary but this is totally useless for tuning of the ignition map..
