5efhe Running Lean

[dexter_5000]

i have 92 paseo and its running lean with a 5efhe using the stock 5efe throttle body, injectors, wiring harness, and ecu. any ideas what the problem is?

just cos i am a noob...

what type of engine is a 5efhe?

[Boro Sera]

5E-FHE is the engine used in the Sera. it's basically a slightly higher powered version of the 5E-FE which most of the paseo's have !

5e-fe injectors are smaller than the injectors on a 5e-fhe, could be problem, why are you using 5e-fe throttle body, isn't 5e-fhe one better? the ecu's might be the problem aswell, woulda thought they'll be different aswell. how comes you've got this setup? different fuel map and *******

this is the setup i was told to use for the stock ecu i live in the states its not as easy to find a j-spec ecu and wiring harness intact. what octane do you guys run in them? what is the gap supposed to be on the plugs?

[toyotasera.co.uk]

plug gap 1.1mm

maybe its something to do with the increased compression ratio in the 5EFHE over the 5EFE?

5EFHE injectors are 225cc, 5EFE injectors are 185 or 195cc.

I have some SERA ECU's available - 2 plug 5E-FHE type.
