maftpro is working

[drjonez]

FINALLY, i've read all 18 pages (yes a mere 18 here ) and i still have a car specific question. I'm in the proces of getting my 88T up and running. Other then my RC550's, SP61GT@9psi and a 3 - 3.5" DP (approx ) my car/engine is stock (yes a stock non metal HG too). I have a Lexus AFM but it's not installed yet. Engine isn't even running yet.

Now i've been told before to get a Walbro, FPR of some kind and SAFC. Now i just hate the flashy looks of the HKS stuff since i think it doesn't mix with the supra's interior.

Anyway, my question. I will purchase a Walbro pump and a MAF-T Pro with boostcontrol and Wideband going for a speed density setup. But do i still have to get a FPR or would that be redundant ? I'm sure i will be upping the boostpressure to about 15 or so but not anytime soon (need to break it in first).

Any insight ? Need to get my shopping list complete

i don't see anything wrong w/an AFPR. personally, i like to have as many tuning parameters as possible. think of fuel press as a global AF scalar- increase pressure to richen it up, decrease to lean it out. since i like to minimize AFM corrections, i try to get as close as possible with FP and then fine tune via AFM scaling (i.e. MAFT pro, SAFC, etc.). if you do get an AFPR, be sure to get rid of the J block return restriction.

i can actually source all those parts for you (MAFT pro, walbro, WB, AFPR), if you like. drop me a line....

hey, when i'm using the AEM UEGO with the MAFT PRO ... which output-signal-setting do i need on the AEM? -> P4 ?

thanks

 

[turbobob]

I don't have the AEM documentation. Can you post some details?

Which AEM exactly, as there are several.

AEM UEGO Gauge

this is the manuel with the available settings... P4 would be perfect, cause i could eliminate the stock lambda too

[turbobob]

P0 is what the unit is programmed for.

I could implement P4, but everyone wants me to stop changing things and make an official release......

Set it for P0 for now and get things running.

[Matce]

damn ... so i need the stock lambda-sensor too for the stock ecu? ... damn... i would definitely be down for implementing P4

 

[turbobob]

let me get 4.80 done, and I'll spin you up something special......

[Matce]

thanks - that would be awesome

im going to install the thing in min. 14 days so no stress - thanks buddy!

yes. w/the AEM set to 0-5V, you'll need a NB sensor for the stock ECU.

realize that there is a lot more resolution in a 0-5V output than a 0-1V output, so it's to your advantage to use it for tuning. this is a good example of why the LC-1 is a better option- it has 2 outputs.

 

[Matce]

hey ... so i finally ordered today ... are there any readings for maft-pro/ecu-tuning-newbies... which values are what for? critical values and so on ...

@turbotom: if you could manage the SW-release for using AEM/P4 in about 2 weeks for me... that would be really awesome

thx

figuring on 3 settings..........

1 - launching on the 2-step.
2- shifting with foot-on-floor ("NLTS")
3 - protection for you N2O guys, never hit Fuel Cut with N2O spraying (or alky)


Where would you guys set #2?????

Bob

so anything happen with the 2-step?

since you say this would you say to use the lc-1 to replace the stock o2 sensor, and just run one sensor?

that way it's tunning off one source?

The Zeitronix ZT-2 has both a wide band AND a narrow band output I have been using to delete the stock o2 sensor since I first got the origional Maft and then the Maft Pro. It works great, the narrow band output goes to the ecu and the wide band output goes to the Maft Pro.
The ZT-2 has awesome software included for data logging also, I think it's the best wide band for the money.

 

[pimptrizkit]

thanks arron, i'll think about deletin my stock o2, does it set a code by any chance?

 

[bigaaron]

thanks arron, i'll think about deletin my stock o2, does it set a code by any chance?

Only if you have the 89+ ecu, but a $.10 1/4w resistor 1k ohm will get rid of the code.

not at the moment.

the LC-1 has 2 completely programmable outputs, simply program one of them for the std. NB output.

Just wanted to let those of you without a laptop know that you can cut down the motherboard connector from an old ATX power supply to make a spare connector to power your Maft Pro with when you need to update it.

This makes it a bit easier to update your software with your desktop computer, and also gives you a boost harness connector (although without the latching clip it may be inadviseable).

I think this is self explanatory enough. The one thing to note is that you do need to cut off the latching clip from the connector.

OK, I read everything. What exactly is the total cost of the speed density unit with boost control?
