Current setup:

1.4litre, standard engine
standard IHI turbo at 0.8bar only
(later change back for my forged 1.6litre (or maybe 1.9... ) and my hybrid K04, but now i have no time to do it)
440cc/min RC High-Z, EV-1 type injectors (already have 636cc/min Edelbrock 3686 (Siemens Deka4) High-Z, EV-1 types too)
Walbro 255l/h fuelpump
FSE PBV RR 1.7:1 FPR
Renault Master 2.8dCi FMIC
60mm freeflow decat'd exhaust with only straight thru type endmuffler for ALS compatibility
60mm boost pipes
Bailey's DV26
Running with standard 95octane petrol only
(here this is as standard 94% petrol and 6% Etanol from 2010 december, further was 95.5% petrol and 4.5% Etanol)

Megasquirt2 v3 standalone ECU + Innovate LC-1 WBO2 system

not yet finalized, but for a base, or for daily usage is good

engine: standard 1.4litre GT3
injectors: 440cc/min
fuel: petrol, 95 octane

When I connect my MS in the car and at idle the car runs beautiful. but when you open the throttle and the car is not at all not going to speed.

can someone please send settings for outputs and enrichments? Thanks

Your req fuel is not good. VE at idle around 20 and WOT around 90?!
Or injectors too big?

[kubito]

Ok to check your vr sensor is wired correctly the best thing to do is download "Megatunix" this is a lot like megatune but it has a handy tooth logger.

http://megatunix.sourceforge.net/

Once set up get your engine running and enable the tooth logger.



IF YOU GET A LOG LIKE THIS THEN YOUR SENSOR IS WIRED BACKWARDS!!!! When wired right you will get a single spike instead of the two. The car will not run right if your log looks like this.

My log looks like this. what I must wired??

in the msq file is all settings inside, just load it in your dekstop PC or notebook and check them
don't need to upload in the ECU

have you configured it in right?

MAP sensor type 115kPa, 250kPa or 400kPa?
WBO2 is in lambda or AFR?
temps are in C or F?
sensors are calibrated?
...

once i've just misstyped a box... 2 days long searched my fail in the settings, and the failure was in the configuration

[kubito]

I think my settings isnt good because car doesnt running well.
I have MAP 250kPa
lambda Innovate LC-1 on idle-16AFR
temps in C
sensors are calibratet I hope well

Sounds like the vr (crank sensor) is wired wrong, swap wires.
