77 280z N/A ecu with l28et

[JonnyZtalk]

I recently dropped in a l28et in to my N/A 77z I herd that you could use the stock N/A ecu and harness if you modified the fuel injectors,use the stock na oil dizzy shaft. and the MAF. I put everything together and the car runs with a lope idle then dies if I give it any gas. I could use any help right about now

The engine will never run right. Use the 280zxt electronics.

Can you list what n/a parts your using?.

 

Which Maf are you using?. Did you do a turbo Maf gut swap?.

 

Are you using the n/a distributor?.

mine runs perfectly on the 77 n/a setup just requires some modifications to run ribht

your need to do 2 things.

 

lock the mechanical advance in the stock distributor and set the timing to 30 degrees at idle. You will need to disassemble the distributor to get to the mechanical advance system. then there are multiple ways to lock the mechanical advance (wire, glue, welding...) FYI, stock initial timing for a turbo engine is 20 to 24 degrees.

 

get a 8:1 FMU off ebay ($100). When you add boost, you also need to add fuel. The fmu will increase fuel pressure while on boost, which makes the injectors flow more gas. so at 8 psi of boost the 8:1 fmu will make 64 psi of fuel pressure. This is about all the stock efi pump can handle.

 

this will work OK for stock boost (8 psi) and 7.4:1 cr.
