Help me choose an ECU

No it doesn't. There are a bunch of options for mounting it though. I have the first produced RE-Speed adapter tower with the -10AN fitting on it for both pressure and temp. You could also just use a generic -10AN coupler with an 1/8" npt port. I would kinda prefer to know what the temp is as it exits the engine, rather than as it goes back in. I think that information would be more usefull even if it is scary as hell.

Stock one won't work. You'll need to get something that latches to grnd.

Same thing, need something that latches to gnd.

Suck it up man, get the AutoMeter replacement senders. They're Delco or Dephi replacements for like $90. It's good info to have ESPECIALLY on a boosted engine. You know my history. With pressure vs MAP you can make a correction table that could keep you from chunking an engine.

On the MoTeC's - yes

CAN bus is the way. Setup is specific to the combination. Which dash are you going with?

I'll check it out in a bit..... going to weld a fuel cell

Okay, I'll add it to the list of crap I need to buy still.

SOB... alright, well add another to the list, I think I'll be saying this a lot.

Same thing, need something that latches to gnd.

+1 to list.

to the list it goes

On the MoTeC's - yes

For future reference so does the Platinum series ECU's from Haltech.

CAN bus is the way. Setup is specific to the combination. Which dash are you going with?

I'm just going with a simple Racepak IQ3 display dash (no logging capability built in to it), but it does has some nice features for not tons of money.

I want to TIG too! GL with it! No contaminatin' the metal with your man juices now.

Hey B,
what sensor are you using for sump level? I've found some SS floaters for around 100, but I think that might be over kill.

[TitaniumTT]

floaters...

Using the stocker

I thought you said it had to be two wire? Doesn't the sender only have one? I'm so confused.

[TitaniumTT]

Well, I'm going to try the liberal/dem approach here and say, well, yeah I said that, but I didn't really mean it

The stock sender must ground itself through the oil pan because when than circuit closes it latches to gnd. I've got that wire hooked to a digital input

Vex... He convinced me to go MoTeC... youre just delaying the inevitable
But HOT DAMN!!! I cant deny its pricey. Haltech was my second choice. I have had some local experiece with it and it seems solid and very capable. The guy is running the E6X though. I think the new Platinum series is even more capable though.

Yeah, I'm going to run a PS1K (I'll have all the inputs/outputs I'll need)--for now. Factoring in my timeline for my final plans with the car there's really no need for me to go Motec now (later... yes... maybe...depends on technology).

As for my sensors I think I have an easy question that will put my confusion to rest:

Out of all the stock sensors what can I keep, and what must I replace?

What I know I can keep:
Low Sump Level--May need some work
Coolant Temp Sender
Thermocouples (will need amplifiers)
Wideband O2 Sender/Controller


What I know I need to buy:
MAP
Low Coolant Sender
Oil Temp Sender

If it's not listed add it in.
