Smile anyone running EMU on a stock car?

I am wondering since i have the damn thing working now, if anyone is running the emu on stock car? I would like a bit more power out of it but am not sure which maps to change. Can anyone provide maps for a 1.8 motor in stock condition. since i put in the EMU it feels bit slower on Low RPMs. I am just learning about the EMU and could use any help possible. Thanks

has anyone run the EMU on a stock motor at any point? if so, did anyone else feel less power in lower RPM?

I did for several days since I installed the EMU prior to the turbo. Simply left all the maps at zero. Didn't detect any change in performance good or bad.

i am just wondering if i can advance the timing on it for some extra power? I also will need some base maps to start on when i do turbo the car i am wondering if you have any laying around to give away? the care will be running stock fuel pump with 460 cc RX7 injectors on 93 octane gas, it will be intercooled, 3" exhaust all the way. maybe if you happen to have one you can spare let me know please.

Don't want to sound too negative, but if your tuning the EMU yourself then you really need to sort out your own maps.

On my car in exactly the same setup i have 2 different maps for summer and winter.

The chances of someone elses map working efficiently on your car is almost nil.

Do you have wideband fitted?
If so it's even easier just activate Autotune,
Input your desired AFR's in the Autotune map
Drive for 15 mins using the whole rev range.
Deactivate Autotune and your done.

If you don't have Wideband and you plan on tuning your car yourself then either buy a Wideband O2 as soon as you can, or sell your EMU as without a gauge on your AFR's it's virtually useless as a tuning tool.

If you plan on getting your tuner to tune the EMU, then i'd wait till everything is installed, otherwise it might start getting expensive in Dyno sessions.


Cheers

he is not online often, but we are building together...so ill butt in if no one minds...he doesnt, he's a cool guy
the car is an '01 and it will get a WB very soon, not sure if he is going with AEM or LC1, not sure what he ordered...here is whats going on, he just got the car running with EMU thanks to here, but it feels slower in the lower RPM range (1500-2200 i think) so until he gets the WB, is there a way he could fix this or should he just wait to get the WB and then fix it?

If the maps are zero'd as they should be then theres no difference in performance.

A 0 in the EMU means that it's not adding or subtracting anything from the stock ECU config.

If you've set up the config car/engine type it should be exactly the same.

01's seem bloody strange with EMU's.


There's bin some that no matter what they do they can't get em to run right.
Others have no problems.

I believe the general consensus was that the latter cars various sensors and electronics were more sensative to the various voltage drops caused by fitting a EMU between them.

As i say check your using the correct engine code and if it's zero'd out it should be fine.
