Gday just wondering if anyone could help me out! Iv pulled a bigport 4age, ecu and loom out of a running ae82 and put it in my ke70 along with 20v quad throttles. It starts if u give it some throttle but runs like shit and doesn't idle, any help would be much appreciated. Cheers

Mechanically sync the throttles.

Check for vac leaks.

TPS adjustment.

Then get back to us.

So a standard bigport ecu running quad throttles? 

How did you connect your map sensor?

Why do people do this?  I know it looks/sounds cool, but the grief is just not worth it...   I'm all for running a 4AGE, but with a stock 4AGE run a single t/b.  Yes, I know you have a fwd intake, either find a rwd intake, or engineer your air cleaner to work from a fwd manifold.   IT is SOOO MUCH easier, AND it will be turn key (everyday) reliable too!

 

 

apologies for my opinion.........

Get aftermarket engine management so it can be tuned properly and take it to a professional. 

I remember years ago some guys over at AE86dc got the quads to run on a bigport ecu, but i dont think they ever got it to run properly.

Yes dont do quads unless you've got or plan to get programmable management.

Not exactly relevant since I know what you're trying to point out, but blacktop 20Vs are MAP so there is provision on the quads for a vacuum line

I have a m48 motec just trying to gather the funds to wire it up so just trying to get going so its drive able till then

Ke70dave I have a vaccume block,

Littleredspirit how do you adjust tps correctly?
