The time has come for me to turbo the tc. I need to get some information about some issues though and have read many threads, but not got any straight answers from them.

A. Why does the ZPI stage 0 through a CEL, but from what i gathered the stage 1 and dezod's kit does not?(e.g. Manifold, E-manage, Downpipe) And how can I effectivly get rid of it?

B. By adding E-manage, will I be able to get rid of a CEL and/or run a atmosphereic BOV? And are any options needed to correct these?

C. What all is absolutely needed with E-manage to correct the AFR from being to lean/rich? And who sells them already setup/instructions to setup, to already work for the tc?

I am very familiar with turbos and may build my own, but the ECU and management required for these cars are beyond me .Please help me get some straight answers(Sciondad, Dezod, ZPI, anyone else possessing this knowledge) !!!! Sorry about the length everyone.

#1

CEL is the result of either two factors... The ZPI stage 0 runs pig rich, which sometimes upsets the primary 02... as it doesn't run a management piggyback... and, all kits eliminate the precat, which sometimes tweaks the secondary 02 sensor, which flags an emissions code, saying the cat is below efficiency (because it's not there anymore)

^ Both are easily fixable, just need to be aware of.

#2

The Emanage is a piggyback that allows you to tune your A/F and engine parameters.. , you should have no problem running at atmospheric BOV with the setup. and the CEL for running too rich (like the ZPI possibility) is fixable with a good Emanage tune, and a Antifouler mod will correct the second possible CEL

#3

The Emanage needs to be tuned with a good Fuel/Performance "map"... if you go with a stage 1, all setups come with a base map, which is suggested that you have tuned further at a local shop for best performance... To tune the Emanage, you should know what you are doing extensively, so most guys let a reputable shop do Emanage MAP touchups for a decent price.

Any more? I'll help you out!

I'm a ZPI supporter to the extreme (Great Stage 0 Starter Kit to build on), but you can see info from Paul at Dezod and others as well... We all help out each other the best we can.

I. A turbo system can cause a number of different CEL scenarios, but depending on what CEL you receive, that depends on the plan of action to solve it.

If for example, your receive a CEL from lack of a catalytic converter, you can elect to run a mechanical or electrical O2 Simulator OR just install a converter in the system. We currently where the 1st company to offer our downpipe with an option of a catalytic converter for such a reason.

II. Adding a E-Manage will not solve any CELs. The E-Manage is to help electronically facilitate your fuel cruves inconjunction with your turbo's specifications. The E-Manage is a tuning device and nothing more.

THe E-Manage has the option of adjutment for an atmospheric BOV, BUT it does not work that well. The real key, we have found is to where you retrieve your vac source for the BOV. We found that tapping the TB below the throttle plate yields the best reults.

III. With respect to the E-manage, if you purchased our kit, it comes pre-wired and with a base map to get your tuner rolling. So not much else is needed in terms of set-up. We offer FULL, TRUE plug and play harnesses for the TC to make install a snap. If you purchased an e-manage and harness from us, I can have it all set with jumpers and rotary dials for you free of charge.

PM me if you need anymore help.

 

Depends on the CEL.... LoL.... for a setup on low boost without engine management, rich conditions may mess with the first 02, so running an emanage with a good tune and leaning it out a bit will fix the issue... That was what the emanage fixing a CEL was in terms with...

Only two CELs I've seen commonly are either the first 02 on a stage 0, or the Emissions code on the 2nd O2... which a 5 dollar antifouler does a great job with...

You can get a harness for the emanage to make install much easier, which is a great suggestion, but does add to the cost a bit, as does the option of the cat in the pipe... Both are great items, which, for a price, help out altogether...

Dezod had one of the first emanage harnesses out there, but there are a few A/M that have now popped on the scene as well...

All stage ones out there should, and to my knowledge, do (except for the GReddy) come pretuned with a good base map and set up with jumpers and rotaries... It's still a good suggestion to tweak it a bit at a local reputable shop though, as you'll see better results.

There are a couple A/M companies with manifolds out as well, and seperate components, but buying a kit gets you additional support, which I'm sure you'd appreciate.

Well, I have seen a number of different codes from turbo and sprayed tCs.

One local guy that runs a 50 shot had 6 different CELs.

True the anti-fouler, as mentioned in mine and your's posts, SHOULD work for a catalyst failure CEL. The EPA cracked down on companies like Casper's Electronics for sell the electrical O2 sims, hence why they stopped selling them.

Your best bet is always pull the code 1st, and then react accordingly.

Happy modding. Holler if ya need me.

 

Gotta love the OBD-II reader and diagnostics... good cheap option here that serves me well... check your codes and watch your engine!
