Leaning Out and stalling
 

Hey guys, I have 1.6 94 NA TD04 Turbo, i was running it fine with the stock ECU and a Piggyback, this week i installed a couple of BOSCH EV14 550cc Injectors and a Speeduino v0.4 ECU (i know im posting on the megasquirt thread but theres no Speeduino thread).

Anyway, got the car to start, idles "okayish" but leans out and dies when after start enrichment ends.
Can´t figure out why tho.
Duty cycle, advance and spark stays the same.

Also big chunks of thottle is okay, but light throttle blips imediatly stall the engine.

Attached the tune and a log, any help is appreciated.

Thanks

Hello,
Your required fuel calculation under engine constants is entirely wrong. It's set to a 350cc engine and 30cc injectors, and presumably wrong dead times. Look over all the settings in "Engine Constants" and in "Spark Settings". make sure they are set correctly for your engine and trigger wheel.

Hi Eric, thanks for the comment, the required fuel is correct for my injectors (5.0ms) and 1596cc and 537cc injectors, dead time is also correct from bosch 0.788 ms.
Spark settings are all correct! Trigger wheel is selected miata!
