Wc34 Stagea Automatic Ecu On R34 Gtt Manual Motor?

[syncade]

Ive been searching for a bit and i cant find any solutions to my problem. I currently have a WC34 Stagea Automatic ECU running my manual R34 Skyline GTT drivetrain. This is all installed in a USDM S14, running fine and everything. I was wondering if the fuel and ignition maps are very different between manual and auto ECUs. I know most cars (such as z32) have completely different maps between transmission models, are RB cars the same? Am i losing a bunch of power and fuel economy? My 02 readings are right on, but the car runs through fuel like a diesel!

I appreciate it the help gents.

I don't have a direct answer for you but ... there are a number (3 or 4) of different Stagea computers although all appear to have pinouts like the R34. For example mine is numbered OV300 and I have an auto with an RB33 series 2 engine. Your best bet is if you could borrow a Skyline R34 GTT ECU and see if it runs differently

Hmmm. Theres definetly no way for me to borrow one, barely anyone in America runs RB25s let alone Neos. Ill have to check what my ECUs Part Number is and post it on here. What do you have your ignition timing set at? 15* or 20*?

Factory is 15* for both Stagea and Skyline R34 but if you're looking for economy just keep advancing it until you get detonation (Knock or pinking) and then retard it a little. I'll look out for a GTT ECU but must say Stagea ones are easier to get hold of (I'm in NZ). My Stagea is probably heavier than your car but I only get about 15litres per 100km (that should take you a while to convert to MPG)!

(later) I had a quick look on the auction site but plenty of ECUs but not R34GTT. I could possibly locate one for you if you are real keen (probably $100 to $200). Depending on your financial situation the ideal solution would be an Apexi FC which would replace your ECU and be completely programmable for most everything (often available on Ebay) for around $1000 ...here is a local example:
