Hey guys, i'm looking for a base load & crank map for my car; i recently rebuilt the motor and changed injectors from 850cc all to 1600cc secondaries, and i half-bridge ported it. i can't get the thing to start, and i was just looking for a baseline map so the thing will fire up, and i can tune it from there. i turned the fuel pressure regulator to about 35psi. i'd really appricate any help, as i said, i'm just looking for a baseline 'cause i've gone through one starter and a set of spark plugs already... wants to start, but i just can't get the fuel right. thanks.

 

your post confuses me.


so you have 2 850cc and 2 1600cc?

or 4X1600cc?

 

i have 2-850cc and 2-1600cc

My map techinically isnt going to make your car start.

Take the spark plugs out.
Squeeze some oil in to the leading holes(front and rear rotor). then stick the plugs back in it. put my map in it. see how you go.

 

i fired her up yesterday; had to pull start her, afterwards she was good until she flooded one rotor lol. i'll try your map, and see if she'll idle. thanks again.

 

my map wont flood your engine.
Did you try some oil in the spark plugs? that will eliminate the need to pull start.

 

Wat would be a good base map in a street port engine 2 850cc and 2 1600cc with stock twins on a lt10 with the x4

 

use the above map.

 

Are you running an lt10? Did you had to put any resistors on the injectors or it didnt need it? Also do you have the x4 box for the coils?

 

no need for any resistors.

 

? for rx72c, can i use this map on a S5 pport?it has the same size injectors but i'm using a mt4 or can you supply me with one?THANKS!!

 

peripheral port?
What injectors do you have?

 

yes peripheral port and i have 850 & 1600cc injectors.

 

I will upload another map that is slightly modified for the pp

rx72c your map has made a world of difference but it runs rich thru out the entire rev range.Can you adjust the maps to lean out some?What screens/maps should i be looking at to adjust for final tunning?Also my o2 senor reads 14.7 afr all the time.I replaced it/ checked the wiring but still reads that ratio what could be wrong?THANKS!!

 

you need a proper wide band sensor.
What makes you think its running rich?

You use the load map to lean out both cruise and WOT and the idle map to adjust the idle.

 

i'll break down a get a wide band sensor.Strong exhaust fumes leads me to think its running rich.I'll play with maps see if can lean it out some.THANK YOU!! for all of your assitance.

 

exhaust fumes?
lol you got a pp.

that map should actually be very good in terms of mixtures.

 

U R THE MAN!!
That map is very good as you stated, but i don't want to be fooling around with the settings too much i'm new to FI and don't need anymore headaches,must be from all the fumes?
I'll keep you updated and i owe you a bunch of for your services.THANKS!!

 

Could i use the same map u recommended for jacoolv6, who has street ported motor with 850s and 1600s with stock twins, while I also have a street ported motor but Im using stock injectors atm with a GT35R single turbo setup?
Or should i use that map but just richen it up all round? by how many points richer too?
Thanks

 

Stock injectors is a different map.
Message me and ill put a map together for you. I need as many details as possible.

 

hows that map comin' on rx72c?

 

Sorry man? I dont think i got a pm from you with all your details?
Send through your details.

 

Sorry, i sent it twice, ill try again now.

Here's the message i sent anyway incase it doesnt go through.
Thanks a lot hey.

Base map for GT35R FD

--------------------------------------------------------------------------------

Hi,
thanks in advance for your time. It's really nice to see someone who knows that microtech system helping guys out so much, good on ya!


I'v got a 93FD, fresh motor still running atm.
Street Ported
GT35R (0.64 a/r hot side)
MicroTech LT10s (Im using a dynojet wideband for AFR off one of my race bikes, abt the best wideband system you can buy)
Stock injectors
Pettit Coolcharge SMIC (AIT abt 45degC/113degF)

It's battling to hold a steady idle for longer than abt 5sec before it leans out, big flat spots as you touch the throttle it leans out, then super rich. Main problem im having is when its in vacuum, AFR is all over the show and stumbles a lot.

What are the ideal AFRs for boost and vacuum?

Is there a process I need to go through to save the map to the ecu once I'v typed all the values in? Or do i just unplug the laptop and dongle?

Thanks,
James81

 

Ok i got that pm.


It would be easier if you can do a screen capture of your existing map. And i can fix it up for ya.

connect your laptop and do a screen capture of EVERY SINGLE MAP and ill tell you what to change.
