Head Scratcher, what ecu do I use?

[Gh0stk1ll3r]

Hi everyone,

I've just bought a roller project that should be ready to turn key, providing I have the right ECU.

 

The car was a BF XR6 with a ZF 6HP-26.

Now it has a BA XR6 Turbo donk bolted to the original ZF 6HP-26 from the BF.

 

Apparently I can just tune the BF's ECU to run the combo of the BA Turbo and the ZF. Is this correct?

Or do I have to use a BF XR6 Turbo, ZF 6HP-26 ECU and BCM?

 

I rang my local tuner and he had no idea.

 

Thanks for your time.

Does it have to be a factory item? Could you use a aftermarket haltech ecu? I don't know. I don't even know why I'm answering.

[Gh0stk1ll3r]

That's my absolute last resort. Because the plug and play option is 3k.

[I love kittens]

Well is it worth your time and money to try and do it the hard way or get something you know that's going to work. You could always sell the aftermarket ecu when you blow your car up I'm assuming this is a car that's going to see a lot of abuse

[Gh0stk1ll3r]

Car won't see abuse to be honest. Being an unopened BA motor, we all know their limits. Definitely pro looking into making a tuned ford ecu work.

[k31th]

your tuner should be able to make the BA motor work fine with the BF ancillaries, it just won't have a couple of sensors (knock sensor and secondary oxygen sensor, are the ones I can think off of the top of my head).

 

my only question is, why does it have a BA motor in there? somebody's a fair dinkum cheapskate to blow up a BF motor then replace it with a cheapy BA motor...

[Gh0stk1ll3r]

Guy I bought it off Inherited a Original 90,000km BA XR6 Turbo that ran sweet as a nut but had a surprise date with a Captiva in the side. The BF was on it's second motor and blew the head. Picked up the lot for $3800. I'll chuck a bf or fg Turbo motor in it when I pay my ranger off.

 

So back on topic I should be right with the BF ECU?

 

Thanks.

[k31th]

yep, it'll be fine

 

pics and vids when it's all done

[Gh0stk1ll3r]

Will do mate, thanks a bunch.

Or get a bf turbo ecu , bcm, dash cluster, key & barrell, bf turbo engine loom & it should start up thinking it's still in the other car

[k31th]

he has all of that... he's putting the engine from the BA into the BF haha

[Gh0stk1ll3r]

That's correct. Haha

Yeah mate all sorted.

[Gh0stk1ll3r]

Another question mate, will the BA 4 speed LSD harmonize with the ZF? Or will I end up with strange shifting? Cheers.

[k31th]

it'll just be too short of a gearset, realistically, e.g. your gears will rev out too early and your top gear will be too high in the rpm. Best to change it to a 2.73 ratio ZF gearset.

[Gh0stk1ll3r]

Ok so I'll chuck the 2.73 open diff back in it until I decide to get an appropriate LSD.

[NA_TURBO]

I use a 3.45 LSD diff in my BF turbo with no issues. It's quicker off the line and a little more responsive around town but being 6 speed and the last 2 gears being fairly high it doesn't run out of legs, it only just gets into 4th at 150ish kmh at the 1/8 mile drags

[k31th]

not annoying on the highway cruising?

[NA_TURBO]

Na it's quite good actually, been to Adelaide with it (450kms) and back again a few times and it's good on fuel, not noisy and the ZF didn't seem to have an issue with shifting.

[k31th]

nice work

 

there's some good real-word advice for ya, Gh0stk1ll3r. Stick with the 3.45 until you're sick of it, I guess... and take first gear a little easy

[Gh0stk1ll3r]

Haha will do, thanks for your help fellas.

[Gh0stk1ll3r]

Hi everyone, project is going well, getting close to firing it up. Just checking what I need to do to safeguard my gear pre tune? Like run the NA MAF, injectors and bypass the turbo?

All this is very new to me, I'm clueless when it comes to turbos.

My tuner is an hours drive away, and im hoping I can drive it there, but I'll trailer it if I have to.

[k31th]

there's no MAF, it's a T-MAP sensor; Temperature, Manifold Air Pressure. But you cannot run the "turbo" T-MAP at all with an N/A tune. The T-MAP sensors themselves are not interchangeable at all, physically, either, as they are different pin configurations.

 

You'll either have to run the stock injectors and T-MAP and not boost it while you drive there, or trailer it.

[Gh0stk1ll3r]

Ok perfect thanks very much.

Hey  hey now, my cheapy BA is going to be sweet.
