Does anyone know what types of vehicles came with alcohol compatible injectors? I believe they're known as dual fuel vehicles or something like that. Or what types of injectors are SS inside would be another option. I need water/alcohol compatible injectors. I'm making my water/meth injection system mappable if I can find the above items. If I can't find what I want it's back to controlling the pump rather than the injector. The aquamist High Speed Solenoid isn't an option. Bernard

Yes, I removed three resistors that control voltage to an opamp. I don't have the board #'s for them handy at the moment. You will need to use an ecu with a # of the jwt 450hp control system list. They are easily configured to use a different maf. The older ecu's have the components to control the min voltage from the maf on a small board. I never messed with that ecu's maf settings at all, althought it is easily programmed as well.

I started with a stock fuel/timing maps, then altered for best results. I have not tried any maps from the z32 ecu other than when I switched to the z32 maf I used the tp values from the z32, then altered them. You can copy the maps over and they might work well for you, give them a go and post back. Bernard

Cronic, Magic, what rpm are you seeing your boost starting to climb? Are you seeing 5psi before 3k? I'm trying to decide if I should install my stage 3 .63 housing or give the .82 another go with a new wastegate. I wasn't seeing full boost until 4200 with the old setup but with the vac line off it would come up a lot sooner so I think my wastegate was leaking. I'm planning on 20+psi with water/alcohol injection and I don't want to choke off my power with too small of a turbine housing. Bernard

There are a # of changes you can make but you should first rule out the usual vac leaks, bad plugs, fuel pressure, etc etc. My experience with JWT ecu's is that they usually err strongly on the rich side (10:1 afr's) on the top end. A batronix eeprom programmer is the ticket for a cheap fix if all the mechanicals are ok. You can change the injector latency, the idle timing, afr's, the load scaler.....all kinds of parameters with the z31 ecu to get the idle where you want it.

You can program either one as many times as you want. I have a buddy with the MS ecu. He plugs in the laptop and tunes, I do the same on my car. One advantage I see to the MS is that you can see where you are in the maps while driving the car, but you can figure out where you are in the z31 ecu very easily. But you have to build, or have it built, the ecu and rewire the car. What is the problem with the jwt ecu? They will retune it as well for a fee. Either way you're going to have to know what you're doing, what the car is doing and what you want it to do.

I'll sell you my 280. I'm in Steinbach. PM me. I know of one 240 nearby that can be had for cheap but its a basket case needing everything. Bernard

You can adjust your JWT ecu as well. You need an eprom burner or you can tune it while driving with a romulator from xtronics.com. You can run up to 72lb injectors, and if you want to change maf sensors that's easily done as well. A ford lightning maf will flow upto 1000 cfm. The romulator is 179.00 or so and an eprom burner can be had in a kit fo r 50 or so. Either way you should have a wideband. You can pick up several different kinds of wideband sensors for under 400.00 dollars. If you need help with the z31 ecu tuning let me know, I have some experience with those units. Bernard

Did you try a turbo afm? Can you get it to idle well?

What size injectors? Not the stock 180cc non turbo's I presume?

Why was your old efi running so rich? Just curious as to why you didn't fix it up. Bernard

That's the same turbo I've got except I've got a .82 housing. I like it. Edit: With the 360 deg bearing as the only extra. There's a huge difference between 15lbs and 18lbs of boost with this turbo. You need to run high boost to utilize this turbo in my opinion.

Check here: http://www.speedshopthagard.com for a good price on a turbo.

I'm working at making a boosted launch program for 5spd turbo cars w/ a z31 ecu and have a question. Does anyone know what a two step sets the timing at? Basically I can program a switch into the ecu that will set the timing and fuel to a level that will provide boost at whatever rpm you wish to launch. A push button switch will activate the settings once staged/when you want, let go and proceed down the road/track/parking lot/field. There are several ways I can accomplish this. Desired rpm will be selector most likely. At this point I'm fairly certain I make this work but I need hear a bit from guys with this hardware to see what they have their settings at most of the time. Maybe nobody would use this anyway, aside from me. Bernard

Get the turbo'd Pathfinder going and I'll gladly drive.

Are you/we going?

I was talking about the chopper wheel (CAS) itself. The jy's in California must have a few l28et's kicking around.

What is it going on? Who's tuning it? I'd say they can all pretty much accomplish the same thing up to a point. You can probably get the same hp out of an SDS as a Motec. You can probably screw up a tune as well with an SDS as with a Motec. And what do you consider "after market ems"? There are many factory ecu's that are fully configurable, tunable, have many options for controlling extra's (nitrous, alky, traction control, flat throttle shifts and launches). Many things to consider. The tune is only as good as the tuner. 8) Bernard

jjohart, you can change out your stock efi to a z31 setup by following the sticky in the turbo forum. I find/see z31 ecu's for 20-50 dollars, mafs for the same and then you'll need to source a crank angle sensor or distributor from any z31 or 85-88 Maxima. A maf from a 85-88 maxima will work as well. It's no where near 3 grand. JWT isn't anywhere near 3 grand either.

11-15 ohms = high impedance 3 ohms or less = low impedance

I install mine in the stock o2 location with no problems so far.

I checked my outbox and the messages are there even though I got the error.
