Definitely. Too much fuel, not enough being combusted....
Same thing happened to my B16 because of a busted TPS. Too much fuel (was running rich as hell) and the distributor decided to take a shit on a 6hour drive to new york.....

thats y people with zcs and teg ecus fry their distributers left and right i hope the d15 doesnt fry the d16 dist on my car it runs rich most of teh time due to smaller displacement

geez....i hope my car isnt running too rich. i hope it last for another 6 months till i do more fuel upgrades with injectors and a s-afc
Ok...I think the main reason my zc is running rich right now because I'm running after market cams with the stock crx ECU until i get my chipped ECU back. Hopefully once i get my chipped ecu back it will even out a little bit. What are ways I can get it to run less rich?Phatwhippin_CRX said:

well yes and yes. but teh teg injecters are the same. bigger injecters arent always better when used with a afc and tuned they can be great when used with forced induction.
The Teg ECU doesn't burn up the distributors. It has the same voltage and ground outputs as the ZC ECU, the only diffrence is the fuel cutoff point and different fuel mapping - The Si is 7000 rpm, the ZC and Teg is 7500 rpm. Basically this is the rev limit built into the computer. What more than likely happens in these burnt out distributors is they are the ZC ones that have been sitting around a warehouse for a while, then they are fired up with weak ignition systems (like the oem coil and old cap and rotor) and fry the igniter. The first thing I did before I cranked up my motor was to replace the internal coil with an external MSD Blaster SS and MSD Modified Cap. No problem with ignition. It seems that half the people say the ditributors burn up due to the Teg ECU, and the other half have had no problems. Just my thoughts.....

See it's nothing really to do with the voltage, etc..... I'm pretty sure the excess fuel is the culprit. I mean, it can't be a coincidence that I know a few people that have gone through 3,4,5 or MORE distributors with a teg ECU. I dunno...... I never hear ANY problems with a ZC ECU in there.... ever.

hmm......... good point, but I never hear anything about guys with the SI ECU burning up distributors
i used the 89 integra ecu on my d15 with a broken tps for a good 6 months now. no probs at all. the air to fuel gage is always rich unless the motor gets hot then it's off the charts lean. i dont think the 2 have nething to do with each other. longest drive was about 4 hours. piece.

u shouldnt be running it on a broken tps and it be fine. ur gonna kill ur motor running tha ecu get the si if ur running the mpfi its rich but its mostly stoiche. i use teh pm6 from a 91 si and it nice. not finished with the motor yet though gotta do a secret project on tuesday hopefully it will be done till its tossed aside for my b18.
as for the dist problems check it this way. if ur spark plugs become covered with crap from running rich there is more resistance for the distributers colil to push. more resistance means less life for the distributer. thats how i see it and same with ur o2 sensors rich turn black and die.
