MINES ecu

[zer099]

Got a question for you Calum: Do you have the maping for the MINES tuned GTi-R ECUs? Just wondering because I was thinking of going RT and would like that as a base.

[zer099]

Bump

[Calum]

Yep.

[zer099]

Sweet! Saves me the trouble of sending you mine to look at. Out of curiosity, what all is it?

Also, and I am sorry if I missed this somewhere, but can you use any B14 (pre-'98, GA16 or SR20) for a RT ECU base? I.E.: will the OBD crap work now, or will it go crazy since I have a R with a B14 harness hooked up to it? I hate CELs.

Thanks again!

[zer099]

Bump. Sorry for the dumb questions.

[Calum]

Sorry.

The Mines really isn't too much different from a stock gtir ecu (adjusted fuel and timing maps, removed fuel cut). Its a good starting base, but like working with any already 'tuned' ecu you really need to know exactly what the car they were working with was setup like (stock, etc).

You can use a GA core, but you will get a CEL. For no CEL you need a 95-97 SR federal ecu with manual tranny.

Now that I think about it... there is next to no way in hell i could run a OBDII ECU and not throw a cel. I have none of the emmisions crap anymore. I ran with the stock b14 harness so i can have easy hook up to the car, and an OBDI to OBDII adapter was easy, but thinking about it now switching to an OBDII ecu would be pointless because it would never pass emisions without all the crap that i don't even have anymore, right?

Long question short, in your opinion would it be best to just stick with an OBDI ECU with my setup?

Also, If I go with a b14 or b13 ecu, will I need to remove the resistors for the injectors? Man this is complicated...

[zer099]

Bump for my moron questions.

[zer099]

Yes/no?

[Calum]

Yes, and you will need the resistors for the injectors!

Hey Calum,

After getting to actully drive the car around some tonight and test out the new bin, I still don't know if the bin is right. She runs alittle to a lot lean while crusing, and she acts very funny when you let off the gas from WOT, or anything above 50% throttle, and then give her alittle gas again. She starts to buck and runs at 17-18 AFR.

Is there any way to get the bin off my MINES ECU? I have no problem 2nd daying it to you if you can pull off exactlly what was on my MINES so we can use that bin.

[Calum]

Sure.

Let me send you an updated B13ized version too.

[Calum]

Stock gtir maf and stock 440 injectors at 3bar, right?

[zer099]

I was running the MINES with 444s at 4 bar and z32 maf. The MAF was aracounted for by the SAFC. I will try the new B13 if you like, the old one didn't like things at all. Lean as hell idle and bumpy as hell.

I think running at 4 bar with the MINES sort of counteracted the fact the are tuned for 100 RON from what I understand. Because I only hace to use the SAFC for a slight idle adjust and a small band adjustment from 3-4k rpms at 50% throttle. Other then that she worked like a champ.

EDIT: Oh, and was that a "sure" send me the ECU in the mean time so we can pull the bin? SOrry, just got out of surgery...

[Calum]

Yea, sorry, that was a 'sure, send me the MINE's ecu'.

If I send you a bin setup for the Z32 maf and 444 injectors can you zero out the s-afc settings and set the base FP to 3 bar? Lets see if we can get that to run then put it back to 4-bar.
