Maybe I should not post 5 minutes before my colonoscopy. That procedure is like a ct26 with a blown oil seal. The charge light, brake light, and rear light out lights all are connected together in the combination meter by diodes. The exact wiring I don't know. I.am reading the EWD. If current...

Read the stated problem. No dimming a d all three lights come on at same time. In the dash wiring diagram all three of these lights are terminated to same point. Whe. The diode in an alt is bad 12v flows both ways. The voltage goes to the three wires for these lights and the light up. I had...

I think it's the diode going bad and allows current backwards through the ground which turns on the lights. All three of those dash lights are grounded to the same spot in the diagram.

that's always fun to find out late after installation. I have had bad starters and alternators out of box. now I always test the new starter or alternator right out of the box before I leave the store. installing a faulty new starter in a 1uz is not something I want to do. hal

the 100 amp fuse looks ok even if blown. but it appears yours is good. check grounds especially wires going to intake manifold ground. check that voltage to aem when starting is 12 v. if at 10 v stuff does not get turned on by aem. sometimes when cranking voltage will drop to aem to 10v...

Suprra_girl that appears to be a waste spark smart coil on that link not an ignitor. any waste spark coil may work. but that coil appears to have 3 wires which makes it a smart coil that does not use an igintor but the third wire is a trigger with a 5 volt trigger. that will work with some...

I do wonder with the volumetric effeciency differences in the motors. The 2jz GE head is best. it will flow more air. That may make a difference in the tune in the 2 ecus 7m GT vs 2jzGT or GE off boost. that may be able to be tuned around with a piggy back and a AFPR. i will be doing...

the only difference between a pre 89 engine and a 89+ engine for sensors is on the Tstat neck. i think the ecu temp sensor is different. either that or the temp gauge sensor. so if you have a 87-88 harness put the tstat housing for a 87-88 engine. if 89+ harness use the tstat sensors from a...

2jzge is 3 litre just like 7m. 1jz is 2.5 ltre so why spend the money. stock 2jzge block good for 500+hp. for turbo add a oem 2jz TT head gasket and a ebay manifold or other choice and your good. the ge head has a different exhaust manifold flange pattern than the turbo head. also the ge head...

i have a dual hanger with walbros. 2nd pump comes on via aem at 5 psi. i have run over 550 rwhp on them. i ran -8 to stock fuel rail and -6 to afpr and to tank. i have the arizona dual hanger. ( i think thats right.) i think i can get more hp out of them. hal

ign sync number is at top of ign phase panel. where you input the phasing numbers. this number will change as you set the timing with aem. it will be specific for the position the cps was installed and locked down in. my ign sync would be different most likely than yours as my cps may be in...

On 7m coilpack coil 1 is left pack. Coil 2 is RIGhT pack and coil 3 is center pack. If u can get the car running check ur timing to besure the IGN Sync number is correct for ur cps position.

To be sure check off multiplex. Turn on coils 1-2-3. Set ign phase coils 1-2-3 to 0.5/4.5/8.5. I think that is right. And 12 spark tooth is correct Also the ign SYmc number tells the AEM where the position of the cps is in it's slot and thus what tooth is TDc on cyl 1. The ign Sync number...

The air temp sensor and the stock oli pressure sensor and the oem temp gauge (not the ecu coolant temp) are resistor 2 wire sensors. I bought a 5 volt temp sensor foil my oil as there are no extra reaisitor inputs only 5 volts. In this problem I wired the 5 volts to the sensors ground wire and...

as mentioned the power batt, B+, B1+, main relay pin, and fc pin for the cor all have 12 volts even when the ecu dies. i shorted the main relay and same thing. the power is still on the pins it needs to be. i called a tuner out in CA and he had a similar problem when his map sensor was...

i have run a aem in my 90 for years and tuned well. i rebuilt my engine, wired in 2 5 volt sensors, and reinstalled aem. I put my cal file back in and the car crancked. it ran for about 3 to 4 minutes and died. the ecu was dead and disconnected. The engine wont crank again for 15 minutes...

dan as always has good info. many other mods come first. the lag for a 2.5 inch ic pipe may not be much. i would guess that all the twist may add some time to lag but not much. i have modded all other engine parts first. i just am getting my FFIM installed with a 3 inch pipe and a 4inch...

i like mine. when i have less than a 1/4 tank of gas the walbro gets noisy. that may be because of no return flowing into the center area of tank. aem controls the second pump so its not on under 5 psi. hal

this is a common 3000 rpm aem stutter. i think it is in the multiplex ignition crap. i also thinik it is how the cps is installed when at TDC makes a difference. i got best results when at TDC install the cps so the spinner is about 1/4 inch past the top sensor pole. you may need to set...

On that inj 6. Put one of those inj light tester things on the plug to see if it is pulsin properly. If you have another low ohm inj you could put it on the plug to test. Or switch another injector from ur rail and see if the inj is bad.
