has any one a MAP ecu on a sr20det ...just wandering how you like it etc.. what have you heard

the supra guys seem to love it and its inexpensive if you know how to tune

I have used the MAP ECU on a supras, and sc's I have also installed them on EVOs and on SR20DET. Its just as easy an SAFC to tune if you have a wideband! Just tune for 14.7 AFR at idle and 11.7 at WOT, 20 at Deceleration and 14.7 at cruise. Then you are set!

the thing does this learn mode while hooked to the stock maf to get you a base to start with too..

you convert the car over to MAP-based. Power FC D-jetro is a form of MAP-based standalone. Also F-con v-pro gold or something is mapped based. Other companies are Haltech, AEM. Its not uncommon on an SR, most people just don't want to spend that kind of money on a standalone kit.

Also most Nissans are MAF-based cars that allow you to swap back and forth from MAF to MAP.

He's talking about a MAP converter unit, that uses your stock ecu. It replaces your MAF and lets you tune the car (if you have a wideband, like previous poster said). I'm also interested in hearing from those who have used them, might be a cheaper (and easier/cheaper to tune) alternative to the AEM or PFC D-Jetro.

its like 400$ - so if ur looking for an inexpensive way of tuning this isnt it - but it does let you run MAP

CylonFrakker · 11-29-2006, 08:54 AM

its inexpensive! How much does a SAFC NEO cost? Hell what about PowerFC D Jetro, AEM, HALTECH. Granted they offer more tuning. But the map ecu is really good deal at 400 for what it can do?

kove · 11-29-2006, 09:02 AM

ok well i look at it this way i have a stock mafs on my sr20det and im going to upgrade my turbo etc so if i convert it to a map with the MAP ecu for 400.00...i wont have to buy a z32 mafs which is close to 200.00 so really im payin 200.00 for the system i would say that is a good deal and much more tuneable than a safc..

CylonFrakker · 11-29-2006, 12:00 PM

and get a wideband!

GSXRJJordan · 12-03-2006, 03:27 AM

bingo ~

This actually got me thinkin, because I was about to pick up an AEM setup, but then I remembered how much of a pain in the ass the AEM is to base tune without a dyno. I might just go wideband + MAP ECU and call it a day...

so then I start lookin around, and a few (non-nissan) forums have said that the MAP ECU's dont work with SR20s... which makes me curious, cause I've never actually seen an SR20 with one.

Anyone tell me/us for sure?

I've seen plenty of SR's switched over to MAP sensors.

I'll be running on the SDS EM-4 shortly and I'll be using GM sensors

It's easy on the supra cause the JDM ECU is MAP.

smelly240 · 12-03-2006, 09:07 AM

um... MAP-ECU is a unit - a piggyback... it does work on SR's - and a SAFC is like 150$ - thats the cheapest way (but gay also).

the supra guys that use the map-ecu unit are not using the JDM ecu - or they wouldnt need the unit at all. The reason so many of them use it - is because u cant "rom tune" the toyota ecu's affordably - so they're stuck with standalone or a piggyback. This is one of th efew piggybacks allowing for a switch to speed/density.
