Fresh 6-bolt build issues

[Cmax907]

I just had my 95 eclipse rebuilt with another 6bolt with some goodies in it.. I now have a cold start issue!! My o2 sensor is bad im pretty sure because on ecm link it reads at a steady 0.02volts???? I also think I have one injector ticking only at idle (resistor pack)??? I also was wondering if the 2g 4pin tps should still work with the 1g 3pin tps??? Any tips? just trying to get this thing running smooth? Not to forget it smells helly gassy and idk if that is common with upgraded injectors i have 650's in it now, or im just running really rich?

1. Use the 2g TPS, not the 1g.
2. Yes, if the o2 sensor is sitting almost at 0 it's bad.
3. Post a log.

Welll do you have something to tune with? Bigger injectors at the same pressure is more fuel making you run rich unless I'm mistaken

Change the o2 and then report back if its bad change it because it'll bite you later on.

If you read the post, he says he has ECMlink.

Just as Brian said, you're going to need to use the proper TPS, replace your 02 Sensor, and then set Link properly to accommodate the injectors. This will include dialing in the deadtimes and global scale. Once this is finished, getting the MAF set properly VS the changes in the fuel you make will help smooth out your idle tremendously.

It can be tedious, but once you do it and you feel the difference you make - it's very satisfying.

It's not that a 1g TPS is improper, but it will take another change in link to get it to work properly. Just a better way of going about it.

ive got teh same thing goin on. im about to switch injectors also. im not having a cold start issue yet because i havent installed them YET but is global and dead time and MAF all you need to tune to make it drivable under low to no boost? ive also got ECMlink

 

[snowborder714]

If you have upgraded injectors, just global and deadtime. A stock MAF doesn't really need tuned, especially for idle and cruise. It will make it better if it is, but not a dire necessity to get it up and running.

I sent my whole ecu in to ecmlink and the upgraded it to v3 and put in for the injector compensation. I know how to use that much ive gone through and set some values but without a properly working 02 I really cannot do much so I just ordered a AEM wideband. I will get that tps swapped over to a 4 pin. I read that the cold start could be an issue from thremostat housing wiring since on the swap it changes that up a bit? Im not entirely sure though...
