Hy


My engine is a newly rebuild (did it myself) and has a Judge Ito big streetport.

After installing it I fired it up on the PFC and did the learning procedure (several times by now)

the PFC is on the basemap and my LC1 wideband kit (setup acc Innovative website instructions for datalogit) reads AFR's around 9:1.

Overly rich, the car stinks and guzzles fuel.


I tried to adjust the fuel with the excell recalculation file on the Datalogit Yahoo group but that didn't help at all. After the recalc. the engine was bogging and when reducing the fuel in the lower rpm area, it died.

setup:

- big streetport (intake)
- OEM injectors
- non seq
- HKS twinpower
- PFC + datalogit
- LC1 WB kit

I'm sure it's rich, but is it really that rich (assuming no mechanical problems)? Are you reading your AFR from an auxiliary input into the PFC datalogit box or from the LC1's display? You really should have a separate LC1 display. What has me concerned that your wideband may be wrong is that leaning it out makes the motor die before your wideband shows much of a change in the mixture. I read through all the threads and writeups about the LC-1 and I did not find them sufficiently clear enough, so I set up my own diagram:



and read this thread: https://www.rx7club.com/power-fc-forum-47/my-power-fc-lc-1-xd-16-datalogit-wiring-diagram-707298/ . I'm not sure your exact setup (as innovate offers two different gauges for the LC-1, or you can run no gauge) but the grounding in this diagram is important. Did you set the voltage scale in the LC1 itself using the Logworks program?

what p row is it running in @ idle?

Is this problem at idle cruise, or where?
Figuring out this type of problem is not rocket science but requires methodical checking.

Things to check:
(1) map sensor connections and readings
(2) base fuel pressure
(3) injector setup
(4) complete ignition system
(5) fuel/injector values for the problem area.

If no problem is found, then leaky injectors.

My 3rd gen was also running really rich until I went thru the wiring and made better grounds. it helped alot to have a better source for the fc and the lc-1

Speedworks

problem is that I still have the 6 wire LC1 kit and I only can find the wiring scheme for the 7 wire.

I have the LC1 output linked to the PFC and I have a separate DB gauge, both reading 9's.

I have the LC1 setup for 0.1v = 9:1 AFR and 4.9v= 16:1 AFR


I need to check the P row where it idles but my idle is steady at 900-1000rpm


It's to rich over the whole map. I might give it a try to adjust the PIM setting and lean it out a couple of % over the whole map.

I got the Chuck Tuning Notes since yesterday and reading up, so I hope to find some answers in there.


MAP sensor is OK...

Fuel system has been checked and double checked

The DB gauge needs the default settings in the LC1 which is something like 0v =7.35and 5v = 22.39.

The lc1 has 2 output wires. A yellow and a brown, the brown is set to the above default settings and the yellow is set to simulate a narrowband output with 0-1v range, but either one can be changed to output a 0-5 volt and any settings you choose. You can set one to the above default settings and run it to your DB gauge, and the other you can set to your settings for the datalogit.

Just to be clear, you changed the settings both in LOGWORKS and in the datalogit setup correct?? You made sure they matched?

If you did change both it would at least explain why the gauge is not reading correctly as it needs the 7.35 - 22.39 range.

Speedworks

yeah I put it in both... I figured they had to match

In logworks I put the values in both tabs as well..

do I put your values in datalogit or logworks?

Dudemaaanownsanrx7

iTrader: (23)

yes they do have to match, but the gauge requires the values I provided as it's not programmable. So you have 2 options:

(1) leave your settings the same, except change the yellow wire output in logworks to the values I gave, and then run the yellow wire to the DB gauge.
NOTE* if you do this you can't run o2 feedback, which should be okay cause most people turn that off anyways. That brings me to another question, do you have o2 feedback off? Make sure it's off.

(2) Change your settings both in logworks and the commander to the settings I gave, keep the brown wire on AN1 and also to the DB gauge.

In both configurations make sure you have all associated LC! grounds connected to each other and going to a good chassis ground. The ground wires include one coming from datalogit AN2, any grounds to the gauge, and all grounds except the heater ground on the LC1 which should be wired to a separate chassis ground. (Although I have my heater ground tied in to the other grounds based on a misunderstanding on my part originally, it seems to work just fine.)

the 6 wire is a POS, good luck

Call innovate up. A friend had the 6 wire and couldn't get it to work right, they ended up replacing it with a brand new 7 wire unit

Speedworks

Ok thanks a lot? I will try all of these things.


I mailed Innovative if they could replace mine with the 7 wire as I bought the kit after the 7 wire came out. You should not send customers old stuff if you do that?

Anyway, I didn't get any answer from them.

Thanks a lot

Try all the other advice first, but you may indeed just have a bad unit. Unfortunately it will probably take you a month to get another one because of how long the process takes.

I know you are in Europe so that means a time zone and a language barrier that makes it hard. But you will have to call them up in the US. They will make you do some bullshit stuff you've already done like check your grounds. Just 'yes' them to death if they tell you to do stuff you've already tried. Then you are going to have to try and get a claim number or a case number or something if possible (so they have your information in their database).

After that's done, call them back in a week and tell them it's still having problems. Basically just be really patient with them and let them follow their procedures, until finally they give up and give you an authorization number to send the thing back in. That's how my friend got a brand new one. It took him a few weeks total, and he lives in Texas.

Speedworks

will do thanks, I might tried it over their Belgian distributor (didn't know there was one at the time of purchase) as I'm not going to pay again for shipping it back around half of the world. Then it doesn't make any sense at all.

I'll check over weekend how the settings turn out.

Many thanks again

I had a little thought about the issue with the DB gauge reading and came to the conclusion that it can't be the problem as I also check AFR on my datalogit logging files and it reads thesame as the DB gauge (give or take 0.1)

so if I would recalibrated the output signal for the DB gauge it would be off the Datalogit reading....

Dudemaaanownsanrx7

The DB gauge works with:
0v =7.35 AFR
5v = 22.39 AFR

So if you don't have it configured like that in logworks for whatever channel you have going to it, then it will NOT read correctly. The DB gauge is NOT configurable and works on ONLY those parameters anything else will be false. This is all covered in several places on innovative's website and the manual, as well as common sense. How would a non programmable gauge running off an analog signal be able to magically know what you put as your settings? It wont, and it doesn't.

As far as why the #'s match between the datalogit and gauge I have no answer for that. But the gauge does NEED those other settings to be accurate, so my guess is the readings you get are erroneous and not reliable and either your settings are weird in logworks, and/or the dataloig, you have something setup wrong, or the LC1 has a problem.

Speedworks

Ok so, I would be just fine, putting in the values from the Innovative website as far as for the Logworks and Datalogit to work together (meaning they get thesame 0-5v values to communicate) and to insert the ones you're posting just for the DB output...

Or just be done with it and use your values for all outputs (Logworks, Datalogit,DB gauge)


The datalogit doesn't really care, it just needs 2 values to have a 'frame' to work in) and an upper limit AFR of 22+ is by far big enough to work in.

Dudemaaanownsanrx7

Yes exactly. You have 2 outputs (yellow/brown wire) that you can configure for 0-5v operation. You can configure one output with your settings in logworks, and run that wire to the datalogit, and then configure the other wire with the settings the DB gauge requires and run that to the gauge.

Or as you said you could use the same wire for both the DB gauge and the datalogit and just use the DB gauge settings. The only small drawback to doing it this way is that your original settings would have allowed for a bit higher resolution in the datalogit, meaning it would be slightly more accurate with the 9 -16afr. But its probably only something like +/- 0.001, or even if it was +/- 0.01 it's not enough to be a tuning issue. I personally use 8 -17 in the datalogit because I tune to 16:1 for lean highway cruising.

But the gauge needs its settings to be even close to accurate, I'm surprised with your settings it's reading the same as the datalogit. Thats very odd.

I set everything to read from 9 - 16 AFR.
