nope stock guage getting signal from gm coil pack

thanks

bump

had the same problem, really makes you learn the toe brake maneuver fast!

can someone help me locate the tach wire under the dash. i need to send my rpm signal from an aftermarket coil pack to my stock tachometer, hoping i dont have to remove the gauge cluster just to tap in. 92t so newer style harness colors.

i would have put the magnets on the back of the pulley but it was already made when i got it. then you have to run the timing curve backwards which is confusing ie 25degrees aftdc @3000rpm or so

done, thanks

thanks that might help, do you think the tccs will malfunction without being plugged into the coil pack and injectors? thats basically all im leaving out i just want my guage cluster to stay the same.

thanks colin i think i will have to keep the isc then which will be controlled by the tccs, im planning on running half stand alone and half tccs. my ems controlls tps, map, air temp, water temp, injectors, spark with halltech sensor(timing). but the rest im gonna try and leave to the tccs like...

i think i understand the isc in a very general way which is, the isc uses the coolant temperature to determine extra air added or taken away for idling. can someone shed some light on this for me, i am going to be tuning with stand alone soon and am wondering if this will ruin my fuel values for...

napa auto parts or wichester auto parts its made by spectre i'm sure you could find it online

i just finished installing the driftmotion intercooler kit for 7mgte and thought i would post some pics of how i did mine. first of all you should know this is not a bolt on kit and requires moving a few things, oil cooler, radiator overflow reservoir,and horns. Also i had to buy a cone type air...

i have two guages to read vacuum and boost i have the boost controller wich shows vacuum as a -99 which i think is a percentage and i have my sds standalone unit which shows me my vacuum in inches mercury i believe and that reads -18 at idle and -24 when engine braking they also have the same...

well not the wg actuator guess ill try other options

^LOL i dont think its a vacuum or boost leak in the pipes, i would need to do a pressure test to be sure i guess but i think the problem is in the wastegate actuator, and now i see its not adjustable, ill replace it with my old one and try it out, btw how much pressure can the stock...

i got rid of the old w/g. and i have the bc hooked up the same way i always had it, it seems to work on the initial spool when its turned up and reaches 9 or so psi for a second but then settles back to 6ish psi. when the bc is off it wont go over 6ish at all thanks for the response

hi all i was attempting to turn up the boost with my greddy profec b spec2 my old ct26 turbo held 12psi no prob i got a new wastegate with my 57 trim ct-26 and could only boost over 6psi for a second and then it would settle at 6psi, was wondering if i could simply tighten the wastegate actuator...

i'm not a pro but my machinist told me bigger gaps are generaly for higher hp. looks like you will need lots of boost! he he. I was aiming for a similar hp range with the same pistons and i believe i had mine gapped to .016-.017 which is a little larger than probes formula...

hi all my freshly rebuilt engine seems to be leaking oil from the headgasket which is a brand new 2mm cometic i had the block decked to a ra value of under 20 so its real smooth, oil seems to be slowly leaking from where the timing cover meets the block, and then slides down my mhg and leaks all...

this is off subject but i want to take advantage of your attention, i installed 7mm worth of washers in my oil pump relief valve and in the oil cooler relief valve and my pressure is high 42psi @650 rpms and 78-80psi@3000 what is the danger of high oil pressure and am i near the limit? if so how...
