Hy Guys,

i'm lookin for a PFC base map for my large streetport 13B.

Still on OEM injectors, full non seq turbo conversion and HKS twin power, Trust 80mm DP.

Currently not running any boost (rebuilt engine)

Thanks!!

The base map should work fine until you get it to a tuner. Unless your car is bucking or hesitating bad you shouldnt need to make any adjustments running no boost. If it is hesitating and bucking just add some fuel to the base map. It's unlikely someone elses map will work much better. And def dont boost until its tuned even on someone elses "tuned" map, but you probably know that.

I do, thanks.

But I'm in Europe and rotary tuners are nowhere near (UK is the closest and you'll need a boat)

I have an Innovative LC-1 wideband and it reads now between 5:1 and 8:1 so it's overly rich. The fuel tank goes empty in notime so that kinda says it all.

It kind off wonders me why it(s so rich as I started off the PFC base map.
So I assume that when it was doing the learning procedure, it adjusted the mixture quite a lot.

So basically if I want enrichen the map with 10% I need to fill in a value of 1,1 in the fuel correction map, 0,9 when I want it to be 10% leaner

if it's that rich I wonder if your MAP sensor is bad or something else is wrong. I've never seen a Power FC basemap run that rich.

Do yourself a favor and get the datalogit it will make your tuning experience much easier.

the base settings in the LC1 dont even go down to 5:1. The default settings go down to 7.35. But i suppose you could have changed them, but i dont see why you would want to read them that low, i changed mine to like 10:1.

I also don't see why you would be running so rich on the base map with the stock injectors. I agree with arghx, check the voltage of PIM under sensor check with the car running. You are correct in what u said to increase or decrease fuel, and it will not be easy using just the commander. the datalogit is almost required to get a good tune. Since you dont have any good tuners in the area i recommend doing some research, getting a datalogit and talking to chuck about his tuning notes.

Thanks for tips/info. I do have a Datalogit. That's where I'm seeing the AFR values as the DB gauge shows about 8.4:1 on a constant level. It doesn't fluctuate up or downwards.

i did change the settings on the LC1 programmer according to the 13B manual that is on the Innovative website. And in the Datalogit as well.

or this one

So my LC-1 is configured to

0V -> 9:1 AFR
5V -> 16:1 AFR

So basically it shouldn't read below 9 anyway.
I will check my setting on the LC-1 once again to be 400% sure.

"Index of wires:

LC1 wires:

red +12v, fused 5A
blue heater ground
white system ground
green analog ground
yellow analog output #1, usually used to simulate a narrowband
brown analog output #2, used for a 0-5v signal like the datalogit expects
black calibration wire. this is only needed if you do not have the XD-16 gauge
Serial OUT connects to XD-16 or a laptop
Serial IN usually not used. you MUST use the included terminator plug for this

the blue heater ground runs to a separate chassis ground source in order to prevent electrical noise.


XD-16 AFR gauge

red +12v, fused 2A
black ground
Serial IN connects to LC-1 to get the AFR data

The XD-16 has a button on it to calibrate the LC-1, which eliminates the need for the LC-1's black wire.

Datalogit

AN1 0-5v input
AN2 in this configuration, it will receive the ground signal.
PFC cable connects to Power FC
Serial cable connects to laptop

Engine harness/ Power FC

ECU ground many run an extra wire to the chassis from the stock ground wires
O2 wire connect the stock O2 sensor wire to the yellow wire on the LC-1

Both of these connections are optional. Most people turn off O2 feedback.
If you don't have an XD-16 gauge, you need to hook the black wire up to a switch and use it for calibration, see the manual.



Also note that you must use the Delta AN1-AN2 feature under the auxilary input setup for the datalogit to understand the signal correctly. You also must make sure that the datalogit, the LC-1, and the XD-16 all have the voltage scaled to the AFR range you are using. See the respective instruction manuals for how to do this.

Also see this thread for more info: https://www.rx7club.com/showthread.ph...&highlight=LC1

and here is Innovate's writeup for doing all this, which unfortunately does not have a diagram:

also if you have an older production LC-1 (6 wire) your LC-1 may just be messed up. the older ones had a lot of problems.

Only thing I see is that I hooked up the white and green to thesame ground and not the green to the system ground (which is supposed to be on the datalogit box, right?

Which 'port' on the box should I use then?

hook the green and white wires to a chassis ground together (sounds like you did?) then run another wire from AN2 to the same spot spliced in with the green and white wires.

The white wire IS the "system ground" for the LC1.

Then go to setup > aux and set your voltages according to your configuration. And select delta AN1 AN2

Here is one from a Brit. Can't say how good it is?

Speedworks

my LC-1 is a 6 cable.

yellow
brown
red
black
white
blue

no green.


I find this odd as I got it less then a month ago. They randomly ship out newer and older versions then??

where did you get it from? It was probably old stock from some website. Good luck, the 6 wire ones have been known to have some problems (although not all of them are automatically bad).

Speedworks

I got it from the Innovative website. So directly from them.


Today I went back into the Innovative software and checked the settings on the LC1. Previously I had configured AN2 to be my refference.

0V= 9:1 AFR
5V= 16:1 AFR

so now I configured AN1 as wel to thesame settings.

Went for a drive and the map watch on FC-Edit now gives all 9 values.

I think I had i falsely configured and now it's good. Following this, the LC1 output states that the current map is still to rich over the whole line.

I think all the richness also fault my plugs as the engines doesn't hold idle anymore, drops down and stalls.

I'm going to mail Innovative as well and ask them to send me the newer version.
This, because my DB gauge is not moving a bit (values) when I drive. It constantly hangs at a little over 8 and somethimes changes by 0,1.
Given the fact that my minimum is set at 9:1 AFR, the gauge value doesn't make sense.

next move...


- Going to pick again some new plugs (all 9's)
- mail Innovative
- maybe adjust a non boost field of 5x5 with lower fuel settings and see what gives...


Somehow I feel like I'm far from home...
