i ended up doing the manual swap on my 850r a couple months back and ran a manual tuned rica ecu tuned for 15psi. with this ecu i had problems with rev's hanging, taking forever to start, once boost hit a pound over 15psi it would start bogging down, and it idled from 1100-1300. come home from school last week, and thought what the hell, lets throw the stock R ecu in there..... the car runs a 100x better?! has anyone else noticed this or had this problem?

it could just be the tune. run the manual tune in an auto car and see how it does performance wise.
Hmmmm, you guys suggesting Manual ecu is safe to run on Auto car?
I have a T5M - can I try to run my GLT with the T5M ecu?
I'm trying to eliminate possible issues with the GLT, and this little exercise, if safe for both my GLT and my T5M ecu (st stage 2 tuned) will eliminate the GLT ecu.
Please let me know, would be nice to hear from those who actually tried it.
Thanks in advance.

Done 3 manual swaps - all are running different manual tunes (Rica, Super Chip and Stock UK T-5R ECU) with no issues. Auto ECU worked in all of them but with less then positive drivability results.... Rica tune is probably my favorite as far as overall drivabilty thus far - just my 2 cents though.

i'm going to use the auto ECU. I already have it tuned. I'm thinking that because i am not going to be boostin it wont make that big of a deal.

The off the line smoothness and drop is rpms is definitely improved when using a manual tune*manual swap)
Also no CEL codes but NO Obd 2 functionality
With an Auto ecu you still have Obd2 and tuned auto ecu are cheaper and more abundant.
I have had great success with my Ipd stage 2 tune, and manual TT ecu's

If somebody made a non turbo manual tune i would for sure switch over. But since nobody does, i should be safe to stick with the auto tuned NA ecu?

UM in North America All 5 speeds were Na, So just get an Na manual ecu???
Am I missing something?
And if your asking if you can used a Tuned Na automatic ecu that is fine. But you obviously cannot use a tuned turbo tune of any variant.
Truthfully , Just get a stock Na 5 speed ecu, There really isn't anything a tuned ecu is going to do for you. 10hp? lol.

Well if you count the fact that i get about 30-33mpg from the tune then that's something.

I've been hitting fuel cut in my '98 T5 auto. I have a stock '98 T5M ECU that rumor says has no fuel cut. If I'm understanding the posts correctly, I should be ok running a T5M ECU in my T5A?

Umm, how is the manual ECU going to read the signals from your automatic transmission?
Got a big cock? Let me see it!

the ecu has nothing to do with the transmission. thats what the TCU is for.
So, running a '98 T5M ECU and the original TCU in my '98 S70 T5 auto will have no problems?
