Can anyone help me out with a map? I have a cosmo 13bre large street port, aeromotive a1000 pump, full 3 inch exhaust, fmic, 1000 primary 1600 secondary injectors.

I was dyno tuned on 550 and 1600 with a huge horrible rich spot. I sent my primaries to get bored to 1000 and I am in need of a map. I was running around 16 psi before... Would like to get up to around 18 psi on 93 oct.

Any help is greatly appreciated!


I did search and found a couple t04z maps, but they had different pumps, and was not sure if they would be the best option. Wanted to see if someone had a set up close to this!


Thanks!

50 views and nothing? I will really be needing this later in the week. If anyone has/found something close, or can tell me if they ones I found with different fuel pumps would be close? I guess it would just depend on base fuel pressure right?

Thanks!

Good luck some ******** pissed him off so he wrote microtech support off.
I would do a search through his posts youll find a 1000 1600 map and it will work

I don't suggest you plug in other people's maps and then run the engine under load unless you enjoy rebuilding engines.

Using other's maps as base maps needs to be done with extreme caution. If you do this, I'd suggest comparing the numbers with your current map to at least see if it safely close.

I didnt use an entire map, and do not plan on using it for load either. Here is what I used, previously posted by rx72c. It starts and runs, but will not hold an idle. It dies quickly enough that I cant really tell on wideband if im rich or lean at idle. I would guess its flooding out? If anyone has pointers on where to start, it would be appreciated! I still have numbers in the other screens from when it had 550/1600. I am unsure of where to start with those screens.

Here is a map Rx72c posted with the same injectors you have.
Should give you something to start from.

rx72c- I got it to idle earlier today. Here is where it is at.

30" ~ 2.67
25" ~ 2.90
20" ~ 3.24
15" ~ 3.43
10" ~ 3.62
05" ~ 3.05
00" ~ 3.62
2-20psi ~ 4.95

I am not sure why my dwell times are so much higher than yours. It was idling smoothly at about 1100 warm. I drove it around a little bit, and when coming to a stop, the idle would surge for maybe 10 sec. then level back out at 1100. Afr was 12.3-11.7 or so. Seemed decently smooth. Do those settings seem ridiculous?

I just went out and put your values in, it would not hold an idle. Afr was pegged at full lean. I put my values back in.

Here is my 1000 map

30" ~ 0.81
25" ~ 1.05
20" ~ 1.29
15" ~ 1.81
10" ~ 1.81
05" ~ 3.29
00" ~ 3.81
2psi ~ 4.76
I did not get into boost at all, so that 2psi is probably off, as well as the 00". Does this seem strange? The idle seems strong. Pulls about 15" at idle, maybe 18" I am running 93 oct with premix. Omp is eliminated. I was sitting in mid 13 afr at light load cruise. Maybe a little leaner in some spots. I can post more if you need. I am just learning how to do this, im sure its not exactly right.

Thank you for the help.

bumpstart

if i run 50 % stage value with 1000 primaries i use around . 1.1 -1.3 ms for the 30, 25, 15 " Hg idle and load maps
this will give 1.65-1.95 ms on the handset while not staged
( thats the quirk of how the staging value works in micro algorithm )

that will work well for most extendies with 1000 cc type rochies and around 33 psi on the FPR during idle
( 40 - 42 psi base pressure ( atmo ), 15 -20 "Hg idles )

if your using values higher than this,, then you need to check fuel pressure
or you need to make sure they are 1000 cc primarys

if i was seeing 2.67 ms on the handset pre staging with 50 % staging then i would be using a map with 1.7-1.8 values in it

that is very close to numbers i would expect to see when using later s4/5 ( saturated ) injectors with 50 % stage value

nuimpykid

iTrader: (7)

Fuel pressure is at about 34-36 psi at idle. 39 psi atmosphere. However idle was only pulling about 10" cold. Did not have the car all the way warmed up. I have a sard Fpr. -6 lines from tank up.

I sent these injectors to RC and had them bored to 1000cc. They sent a flow sheet back with them, and they are now engraved with rcx-1000? Something like that. They were stock cosmo side feed 550's.

The numbers I gave were directly from the laptop.

rx72c

iTrader: (8)

with those numbers they are 500cc injectors.
No offense. I just pulled those numbers out of a car that had proper 1000cc injectors

Either that or your voltage is very very low. What is your voltage at your microtech(your injectors share the power wire for you microtech)

red wire on your harness. Should have at least 13.5v

nuimpykid

iTrader: (7)

Can I go by the voltge shown on the laptop screen? Or do I need to actually put the volt meter on the red wire?

bumpstart

yes,,- usually micro display voltage at the micro is fine
but just double checking it at the injector may show up a poor connection and is worth confirming

you should also be giving us the numbers in the map itself,,, or telling us if the numbers posted are displayed on the handset
( as i have pointed out ,, the staging algorithm will be adding 50% to the map value while not staging )

if using the real time display you should also be waiting till the engine is near 80C to get the numbers
-- else they will be all crooked with cold warm up correction



if you go to the idle and load maps ,, what is in the -30, -25,-20 and 15 " Hg bins?
this? /\
or \/ this ?
the lower one is entirely what i would expect from 1000 cc rochys

the upper one is something close to stock injectors especially around idle

am very suspect as to the quality of the injector bore job,, or that these injectors have very significant lag periods

not something i would gamble on,,,, go straight to marren and order the import ( 11mm top ) matched rochies

nuimpykid

iTrader: (7)

The numbers I posted were with the car off/cold. Did not realize that they would change on the laptop based on the water temp correction.

I have not touched the load map at all. It is what I put in from rx72c.

20psi ~ 7.1

The bottom map that you posted is what my 1000 rpm map is. But since my car idles at 1100 when warm, does that make the idle map null? Am I just being stupid? It would not idle on its own cold.

I think I may be an idiot.

bumpstart

the map plots are for every 500 rpm when in matrix mode so the ecu will co-relate the number based on its position between 1000 and 1500 maps

if you get no result with the highlighted direct map , its always worth pushing the plots either side of it to change the ramp

you should warm the car and do all changes to the plots when the maps have no added coolant correction factors

later,,on subsequent mornings the coolant and cranking maps can be tailored and it may take a few days to beat the bumps out of the tune as the engine progresses through warm up


you can cheat the process to learn if you need more or less at problem temps by using the mixture trim up then down to get a feel for the coolant map bumps and valleys

once you establish the correction needed you re-zero the mix trim and put the correction instead directly in the coolant correction maps for the appropriate temps


============


the numbers you have for -30 to zero at 1000 rpm from rx72c here should be also repeated in the 500 ( idle ) map else the motor will stall
( there is a little idle /start glitch that comes with matrix mode unless you match these )

if you do this the motor will run and the map will work of sorts

i disagree however with the main basis of the tune with its staging flags being set to basically all injectors at anything other than idle

its not making the best of the reasons for sequential staged injection
and as such having a % stage at 50 % does not also suit the fact injectors are 1000 and 1600
( 50 % is intended for when all injectors are same )




if you have 1000 and 1600 combos and you wish to retain the advantages of proper staged sequential injection
then the staging thresholds will be 3000- 3500 rpm and around 2 psi
this will be where the 1000 cc primaries will be pushing about 65 % duty
-much like the factory ecu will ,, -give take-
to kick them in smoothly with the secondaries approx 50 % or larger than the primaries then the stage algorithm will work with numbers in the 65-75% regions

=============

if you already have a working 1000 x 4 map then there is an easier way to get the map up quickly if you sub in 1600 secs

the staging algorithm should go to 75 %
this will make the 1000 primaries too rich pre staging ( by 25 % )
the 1600 secs will also make the entire full load make approx 25 % richer
( 2000 cc V 2600 cc each bank )

so,, obviously,, pull 25 % out of the mix trim

this will make the real time idle number displayed on the screen back to the same number it always was with 1000 x 4 map

it will also pull 25% out of all of the full load maps,,, back to the same AFR's it always was with the 4 x 1000 map
however,, you will have 25 % more duty time avail for further fuel should you wind up the boost or find need for more

bumpstart

edit to above,, if you have side feed injectors the top feed marrens/rochys will be no good for you

So from the looks of it, I need to match my 1000 map and my idle map and see what happens. I will warm the car up in the morning and see what happens. Thank you for the explanation on the coolant correction, when I get to that point I will def use your advice.

Rx72c, your saying I should see 13.5 volts at idle? Also, I have a gilmer drive on the car, i had heard that it underdrives the alt pulley.. So what should I try and idle at? Also, like I asked above, since the car idles at 1100 warm, does that mean its going off the 1000 map and not the idle map?

rx72c

iTrader: (8)

are you using normal mode or matrix mode?
is your tps calibrated?

nuimpykid

iTrader: (7)

Matrix. I believe so. It has always been sort of funny. I believe its a cosmo tps, cosmo intake... when you push the pedal like 1/8 it shows full throttle.. is that wrong? It was like that when it was dyno tuned before also. Never knew if it was really right or not.

rx72c

iTrader: (8)

well your applying a normal map to a matrix map. ...

voltage should be at least 13.5 as per handset what is your voltage on

nuimpykid

iTrader: (7)

@ idle it varies. Sometimes it will sit at 11.5 sometimes it will be 14.5. A 180 amp fd alt is going on this week.

Dont I just copy the load map to all screens but idle/1000 and start from there? Thats what the manual says.? IDk.... Its my first time.
