Blue Flame goes OBDII

I still suspect I have compression issues on one cylinder that no OBD2 conversion will fix, but when the right time comes we'll deal with that too.
I thought you had that sorted out. :frown-blue:

Any thought of going Cobra intake after the swap?
I assume this car will see a power adder at some point.

I haven't had much seat time this year and as such, I haven't checked compression for quite a while. I am purely speculating at this point.

The OBD2 conversion will definitely help with datalogging which will certainly go a long ways in defining any changes in the future.

Good progress last night. I modified a stock 97-98 M8 harness to match the sensor locations on this 1st gen. I also removed the pigtails for the IMRCs, EGR solenoid, and DPFE.
I took the liberty of incorporating the trans temp sender signal wire into the engine harness, as it was just hanging loosely in front of the engine. :roll_over:

Here's the complete firewall harness from a 97-98 M8 that connects the PCM to the engine, and body harness/trans harness.
This needs to be installed back in stock location but first a test run of the engine with a start up tune I had from another OBDII swap.
Also a shot of the engine harness in place. Ready to rock !

The start up base tune is required to not only turn off all the deleted equipment in the programming, but more importantly to disable the Anti-theft portion of the PCM.

Keep in mind doing so does not allow the SCIL module delete unfortunately if you want to retain the engine fan control via VCRM and full climate controls via EATC but more on that later.

Ayways, Blue Flame came alive with the new electronics. It fired right up, and idled well. More updates soon ... ::cool-blue:

That is so sick...


I don't care what 4v I'm looking at, the plug wires always look like crap! That looks so clean now...

After a looooon weekend, it was finally time to work on this some more yesterday.

I have the power distribution to the PCM and coils routed, with the addition of a additional PCM relay.
The stock tachometer is wired in using the signal from the EDIS module.
The MAF is wired as well.

Alternator and EVO/oil pressure signals still to be addressed, as well as tons of work under the dash to control the transmission (still waiting on new MLPS from Ford).
Then the front bumper cover has to come off for the VCRM rewire + the EATC module will need some attention to link them both to the PCM.

As I said before, running these engines standalone is cake. Integrating them back into the Lincoln amenities is where it takes work -> time. :frown-blue:

JP, remind me your plans for the fuel pump control ...

JP, remind me your plans for the fuel pump control ...
I plan to use the stock wiring to control a relay setup to power the fuel pump. Basically I plan to use the power going to the stock fuel pump to power the coil of a HD relay which will switch direct power from the battery/alternator to the fuel pump.

I already have the Racetronix relay kit. ;)

The main firewall harness has been re-installed. VCLM (no longer a VCRM lol) wired in, and functional. EVO and oil pressure switch wired in.
I wired in the charging light as well, but it appears the bulb on the cluster is bad ? Same goes for the CEL ?
I need to remove the cluster, and the message center keyboard to check the bulbs.

I was also able to flash the PCM with the start up tune JP provided (using another car unfortunately as this one doesn't have the OBDII port just yet).
The tune does need a lot of work though, the car idles decent when it's warmed up, and doesn't die when in gear (which is a big step up compared to the OBD1 tune that was in the car).
I have a feeling the MAF settings are not correct for this 90MM unit though. Once the diag port is wired in, it should be easy to verify.

The high speed fuel pump relay is triggered simply by ignition right now and the pump stays on when the ignition is on.
Wiring the (-) PCM output directly to that relay doesn't seem to trigger it correctly, so either the FDPM setting in the tune wasn't changed (I will swap back to my tune to verify this today), or that signal needs FPDM feedback to work correctly.

Transmission and EATC still to do. I hope to be done this weekend. Moar pictures then.

Hmmm... it's been a while, but I thought the bulbs were good? I know the charging light has told me when previous alternators have died. I do remember checking for codes before and the CEL light flashed as it's supposed too but that's been a long time ago. I don't recall actually doing a KOEO bulb check lately, so anything's possible.

As far as the fuel pump, no biggie either way... it will be wired with a relay shortly. I don't think there is anything to be concerned about the fuel pump being on anytime the key is on. I know I inquired about a fuel pump controller module but Jim from Weldon told me I wouldn't need one.

One of the first things I'll be doing when it gets back is going through the tune with the PRP software once I verify base fuel pressure. It would not surprise me at all the MAF curve will need dialed in. I know the mod sheet indicated the 90mm MAF as required but if the base tune just used the stock SCT file, it will need remapped as I recall from the last dynotune.

As much as I'd like to have Lidio or Lonnie lay their hands on it, I may just rent some local dyno time if things go right. :rolleyes:

I did all the possible testing for the charging light, and it points to a bad bulb. The cluster is coming out today.
The CEL bulb was missing :eek-large: You gen 1 guys I swear :wave: I guess that's better than black tape ;)

Anyways, the Blue Flame was testing my patience yesterday with the hard wired modules thru the center console, making it impossible to to remove it. :confused-red:

Then it was time for some rack action, as the the trans and floor tunnel harness needed to be removed, stripped, extra wires for the MLPS added, and rewrapped.

The biggest difference between the two computer generations is the way how the singals are returned to the PCM.
OBD1 tests everything against common Ground, while the OBDII does it against its own signal from the PCM.
All accounted for, a dieted 97 harness modified to work with the 93 dash harness as that's how the wires are routed to the PCM.

I also managed to wire in the DLC port, it's permanent location still to be finalized, but we now have a connection.

Couple enchanced DTCs for the EVAP system (or lack of it LOL). But things are looking good so far.

IMG_00000377.jpg

Things are looking up though. Still need to finish the jumper harnesses under the dash, and locate the SCIL module somewhere in the car,
so that the VLCM can control the fan properly, as well as EATC can control the A/C Clutch and blend door. Getting there ....

I'll take the blame for the blown charging light bulb but not the missing CEL bulb. Only two people besides you and I would have had access to pull the bulb for whatever reason. I'm pretty sure one did not and not so sure of the other. :mad:

Umm... sorry about that. :eek:

I presume you're talking of the ASHAM8 module... yeah, it was a pain to install as well.

Ahhhh... it looks so good, even on a lift (it has spent enough time on one. LOL :D )

You're a true genius. :thumbsup:

LOL... EVAP system? What's that? :D

Remind me to ask you about that scanner.

FYI... the AC has not worked for quite a while. It's not been very high on the punch list but I do plan on keeping it. ;)
