Ok. Jeep is at the dyno shop and is getting tuned tomorrow. I'm so excited. I'll get you guys some numbers on what its running. For those of you who missed it, i'm having the ftc1 installed to be able to tune the motor. I'll take some pics and stuff for you guys too.

Cool! Be interesting to see the results.

awesome  , dying to hear how it goes, get yourself ready for lot of questions  - did you end up with new injectors too or you just do the FTC1 first? keep us posted

i think MSD has some standalone MPFI systems (ECU and harness only) that work for 4/6/8 cylinders and they range from $1,200 to about $1,600 - not sure how well they work and if you can use the stock sensors (like crank, cam, tps, IAT, CTS - map will work but for forced induction you'll need one that matches the boost most likely 2bar in this case).

and there's always Megasquirt and the piggybacks for a cheaper alternative.

Unless you completely assemble the unit yourself, I question the Mega squirt as cheap,
I know a dozen guys using it on race cars and none of them were able to get them full
operational for under about 1500 bucks. There are parts like oversize injectors,
good MAP units, wide-band 02 that just add $$. And in the end they are all "tweaky"
weird little tuning issues that come and go, nothing major, no blown engines or that
kind of thing they just get "off" and need rebooted to clear them up.

An SDS is the simplest best performing unit Ive seen under under $2000.

Ive installed MOtec and Electromotive, both run north of 3000 for parts.

Another note, the SDS took the least Dyno time to tune on the two I've installed, < 2 hours.

Just another couple cents worth...

I've seen 1 street tuned in a 1 day track event.

so how did it go - I keep checking this thread so i don't miss the update

The jeep is still at the shop. The guy didnt even get to it till friday. then he realized that the instructions that came with ftc1 is for a 95 and older. I called splitsecond and they said they dont have instructions for the 2.4. The shop apparently cant get a wiring diagram for my jeep. anyone know where to find one?

Chris if the FTC-1 can not be used with your Jeep I would recommend going with the AEM FIC controller. It's also  a PC programmable piggy back controller that allows you to retard timing and add fuel on any engine even the latest OBDII. From what i understand it was developed specifically to work with Chrysler/Dodge/jeep ECUs and has more capabilities than any other piggy back units, they also have a "patch" harness and directions to allow you to patch into your factory harness. The cost of the AEM FIC with the patch harness is approx the same as the FTC-1.

This one is designed for chrysler as well. my guess is that no one has ordered one for my motor yet cause the guy didnt know that mine has a 2.4. doesnt seem like the brightest crayon.

geez, they should be able to figure it out
there are 3 connections that are needed (aside the switched 12v and ground)
Crank sensor
Cam Sensor
MAP connection (this is replacing the stock MAP signal)

they can check the wire colors and voltages at the connectors for these sensors and then splice in to the crank and cam signal ones. The discovery process should take like 15 min.

but in the meantime here's the connections for the 2.4L PCM and sensors

Cam sensor
Orange wire - 5v supply
Black/Light Blue - Sensor Ground
Tan/Yellow - sensor signal

Crank sensor
Orange wire - 5v supply
Black/Light Blue - Sensor Ground
Grey/Black - sensor signal


MAP Sensor
Orange wire - 5v supply
Black/Light Blue - Sensor Ground
Dark Green/Red- sensor signal

PCM Connectors (if you want to splice there so you don't run a bunch of wires thru the engine bay)
Black Connector (out of the 3 you have on the PCM):
Pin 4 - Black/Light Blue - Sensor Ground (this will be connected to the FTC1 ground)
Pin 8 - Grey/Black - Crankshaft position sensor signal (this one will need to be cut and connected to the 2 wires on FTC1)
Pin 13 - Yellow/Red - Fused ignition switch output (will supply 12v to the FTC1)
Pin 18 - Tan Yellow - Camshaft Position Sensor Signal (i think this is only a tap in and will supply the rpm signal to the FTC1, can't remember exactly so it could be that needs to be cut as well - EDIT: i just looked, needs to be cut and connected to the 2 cam sensor wires on the FTC1)
Pin 27 - Dark Green/Red - MAP Sensor Signal (this will be cut and the MAP signal output from the FTC1 will go to the portion connected to the PCM)

the only one i'm not sure about is pin 13 - yellow/red 12v - they will have to verify that it supplies 12v when ignition is on but also when you crank the engine.

this is all you need, make sure they connect the FTC1 ground to the sensor ground and not the vehicle ground.

yeah the FI/C would be a better choice as it also has O2 signal modifier from what i remember.

[sharpxmen]

Scratch Pin 13 and use this

Pin 2 - Dark Blue/White - Fused ignition switched output (run-start)

I remembered one thing that you might want to consider - In some instances (not sure if that is the case with your engine) the PCM will power the MAP sensor after the engine is stopped to baseline the atmospheric pressure - because of that the 12v switched output might not be suitable to power the FTC1, so you might need a relay controlled by the MAP sensor 5v supply and powered directly from 12v (same permanent connection as for the PCM)

In that case use these connections
Relay pins: 85 and 86 solenoid control, 30 12v supply, 87 12v output

Connect Relay pin 86 to ground
connect Relay pin 85 to 5v sensor supply PCM Pin 17 Orange wire
Connect Relay pin 30 to 12v PCM Pin 22 Red/White wire
Connect Relay pin 87 to FTC1 12v (it's the Red wire on FTC1).


EDIT: all  these wire colors are for a 2003 TJ 2.4L, not sure what year is yours and I hope they did not change the wire colors between years like they did with the YJ. Connector Pins should be the same though.

good thing mine is a 03 then lol. Thanks for the info. im getting my jeep back today while i figure this out. hopefully the guys can figure it out with your info. i probably could too.

yeah, it's pretty straight forward once you have the wire colors figured out, that's what i did on mine - made an excel spreadsheet with all the connections and wire colors from FTC1 and PCM, then i used a metripac 10 pin connector to splice into the PCM harness - keeping that plugged in would have the harness function as stock - i used 2 other male/female connectors to make the connections between the vehicle harness and my FTC1, LC-1 and SSI-4 (these last 2 are from Innovate) and then disconnect the one on the PCM harness and connect the 2 from the aftermarket devices there, makes it a lot easier to switch between stock and custom setup.

I'm glad someone here is organized. When I hook it up can I run it without a program running on the controller?

the R4 software is only used to upload the MAP voltage output and ignition timing retard. It can also be used to monitor the MAP/RPM readings and cell  matching (in the 2 tables will highlight the cell that is in use at the specific moment in time based on MAP reading and RPM). Once you have it programmed there is no need to have a laptop hooked up unless you want to reprogram the FTC1.

[chrisjsmith4]

So, still not hooked up. Having trouble finding the time to do it. I'm hoping this weekend.     

Sharp- after I hook up all the wires do I need to install a base program to the box or can I start my jeep?


What do you guys think of just baggin the whole thing and going with a V8. Someone was talking to me about putting a 4.7 magnum out of a dodge dakota in it. Just thinkin for what i've put into it so far I could have done a V8 if I found a good donor for cheep.      Pros? cons?

they would've sent you a pre-defined fuel and advance map uploaded in the device based on your application. When you first start the software create a new user and save the current map for future reference (you'll need to download it off the device). After that you can start your engine and start tuning (or take it to the dyno shop like you planned, otherwise you'll need a wideband O2 and some logging capabilities for MAP sensor and AFR). what wires do you have on your FTC1 (colors and description) and what version is it?

can't speak for the V8, but will most likely cost you more than you expect when you add all the other things like tranny, t-case, exhaust, driveshafts, engine and tranny mounts, all the electronics and wiring that you will need, gauges (tacho and speedo), radiator - just some that come to mind right now, i'm sure there's more.
