Thread: Prepping for MAP conversion

regrounded map an iat sensors independently off the strut bolts and everything seems good now

How are things running now?

I just installed mine and will calibrate the IAT tonight. Hoping to get some good logs in and setup my tables before winter hits. I will not have a MAF come summer. I will post back on my experiences.

So i have a few logs. I have adjusted the load values on the secondary map and straightened out the values so lines do not cross. What else can i gain from the logs before trying to run on SD?

Careful when adjusting it so the lines dont cross, sometimes for what seems no reason at all they will get all tangled up again.. not sure what causes it but it tends to piss me off an from what I can tell is it only does it when you are using the graph. So double check!

I got rid of the MAF last fall before i put the car away. I had to cut the fuel map values in half (100 down to 50 at idle) to get it to run. Not sure if i missed something or what. I set up the IAT table according to my readings with a cup of water and my Fluke temp probe. I did each point in the table to get as accurate of a table as possible. Is there something i should look at on why it would be this far off? I was logging runs with the MAP and IAT connected for a few weeks before switching and everything was good. I will be doing a few things before i will be starting the car again, I just needed it running to get it on and off the trailer.

You CANNOT use the same fuel map style for the SD fuel table as you would for a MAF.

I suggest importing the fuel table from a SD calibration in the startup cal folder.

Will do. Thank you.

A picture explains this quite clearly:


I almost did the same thing when I installed my MAP sensor :P

I have not messed with the software since last fall, while data logging does it log the MAP fuel table value as well? This would help me more accurately set up the initial table. I will update the software this weekend and start poking around to get myself familiar with it again.

Yes, "Fuel Map Value" is logged on the "Data Screen".
