JeepcoMJ Posted November 3, 2010 Share Posted November 3, 2010 we have looked at them, its just not worth it for the tach to work. custom gauge pod is gonna cost well over $100. one single decent gauge goes for 80 or more. it's only $50 for that part. not too bad.

91MJdude Posted November 3, 2010 Share Posted November 3, 2010 could you convert the signal from both the cam and crank with the same unit? Link to comment Share on other sites More sharing options...
JeepcoMJ Posted November 3, 2010 Share Posted November 3, 2010 I don't even know if you need both signals to make it work... oh, you should splice the CEL wire from the zj wiring to the xj dash harness. Link to comment Share on other sites More sharing options...
91MJdude Posted November 3, 2010 Share Posted November 3, 2010 yeah, me either, i though it would pick up a tach signal from the neg side of the coil but it didn't like that on this one. if it was that easy all we would need is one signal converter. but the computer only supplies ground for the coil which would give a tach reading, and only way it would supply ground is if it had signal from the crank and cam sensors. then it sends info through the can bus wires (the twisted ones) to the gauge cluster. its not like a separate wire for the each individual gauge. the cel would always be lit because we are not running an egr. so no light is the way to go, for now... I have a scan tool so i can check all the sensors and read the codes if there are any other than the egr and also the cel would always be lit because the 99 computer wouldn't be getting signal from half the sensors so it would always be on. we would have to have double sensors for every circuit, lol it gets complicated, real fast Link to comment Share on other sites More sharing options...
pilotblake Posted November 4, 2010 Share Posted November 4, 2010 My tach works with my gm 350 in the comanche. I don't rember doing anything special either. edit - I just realized you are fuel injected and running a computer :doh: Link to comment Share on other sites More sharing options...
JeepcoMJ Posted November 5, 2010 Share Posted November 5, 2010 try picking up the current CPS and cam sensor? I mean...what's the worst that could happen? you could just make a jumper harness for each to accomplish this... Link to comment Share on other sites More sharing options...
pilotblake Posted November 5, 2010 Share Posted November 5, 2010 Do you have pictures of the front cross member you built to replace the one you cut out? Link to comment Share on other sites More sharing options...
91MJdude Posted November 5, 2010 Share Posted November 5, 2010 try picking up the current CPS and cam sensor? I mean...what's the worst that could happen? you could just make a jumper harness for each to accomplish this... Yeah I think we are going to try that, I have been searching around on the net, and they run into this same problem on the Tj's when they swap in different engines, most run after market gauge pods, but some had written novak conversions will modify your gauge cluster or something to pick up the tach signal. never got a definite answer so i email them last night. alot more info about the issue though on pirate4x4 and naxja. also found a script confirming what I'm thinking: "Your gauges receive all of their input via the CCD Buss. 2 wires carry the signal from the OEM PCM to the gauge cluster for oil pressure, vehicle speed, engine rpm, voltage. From the FSM: Quote:INSTRUMENT CLUSTER Two basic instrument clusters are offered on this model: low-line or high-line. Both clusters are electromechanical units that utilize integrated circuitry and information carried on the Chrysler Collision Detection (CCD) data bus network for control of all gauges and many of the indicator lamps. Quote:TACHOMETER The tachometer gives an indication of the engine speed in revolutions-per-minute (RPM). The instrument cluster circuitry controls the gauge pointer position. The instrument cluster circuitry calculates the proper gauge pointer position based upon an engine speed message received from the Powertrain Control Module (PCM) on the Chrysler Collision Detection (CCD) data bus. The PCM uses an input from the crankshaft position sensor and internal programming to calculate what engine speed message is required. The PCM then sends the proper message to the instrument cluster on the CCD data bus. The crankshaft position sensor is a hall-effect sensor installed near the rear of the engine, where it is aimed at the trigger wheel attached to the rear flange of the crankshaft. Refer to Group 14 - Fuel Systems for more information on the PCM. Refer to Group 8D - Ignition Systems for more information on the crankshaft position sensor." only thing is if I splice that wire, is it going to disrupt the signal going to the computer running the engine. it is well worth a shot, just have to get a day to tinker around with it. Considering my brother is getting married next weekend, (360MJdude) the one that owns the jeep. Do you have pictures of the front cross member you built to replace the one you cut out? you can see it in this picture, we would still like to add some gussets that connect to the bottom side of the frame to make it more triangulated. also incorporate a steering box brace. just have not gotten there yet to redesign. https://www.supermotors.net/registry/media/834333 you can also see here where the lower mount for the radiator is, acts as a cross member for the frame as well. It was all a tight fit, but we wanted that radiator since we knew it was designed for that engine, no matter what it took to fit it. we have almost 2k miles on the setup everything and it seems to be working as it should, well except for the transmission. but its holding in there.

shelbyluvv Posted December 1, 2010 Share Posted December 1, 2010 Don't remember what motor mounts I used right off hand. I have the napa part numbers at home and will let you know what they are. We did weld mounts to the frame and can get some pics if you would like. Could I get the part #s for the mounts and pics of how you made the new frame mounts?
