Ok, I was going to ask this questions lol. So the speed density harness is the same as the boost logging harness only with a connector for Temp (IAT) sensor? And so if I want to log boost I have to log it using a laptop right?

Since the boost logging harness is for Scanmaster how do you wire it up to the Pro?

Also is the wiring Diagram for first gens (91-93) the same for Hybirds (94-95) or is it different? On fullthrottletect.com then only have the wiring for first gens thats why I can if its the same.

I thought I posted an answer......

I was going to start at -35%.

-40% is a good place to start as well.

yea i didnt get what .62 meant until i put two and two together a couple hours ago

360/580 = .62

(.62 - 1 ) * 100 = -38% is the value i put into mainscale

my car is running OK

its fine for a while then suddenly for no reason the car bucks because it goes lean all of a sudden, this is with no changes to throttle pressure at all

My IAT is in the Y pipe BEFORE my w/m injection nozzle like you said.... every sensor is reading fine

also i cannot get my laptop to see the maftpro at all, im using a usb to serial converter, ive tried comm ports 1 and 3 setting them in device manager and in tuner pro R/T and it still wont detect the hardware, any suggestions here?

PM me a phone number if you want, and I'll call you.

is the lean buck while driving or idling? (Or like 3 seconds after hitting a button)

every once in a while, while saving the settings to memory (3 seconds after you press a button) the unit has to clear a page of memory to save to. When this happens you will feel a hiccup. If the car is idling it may stall. This won't happen if you're not tuning.... (I'll fix this in a future software release)


Did you load the tunerpro that was included with the unit?
Do you have any palm sync software running?
what brand of usb converter are you using?
I tested my USB adapter the other day and it worked flawlessly.

Bob - I really like this, but not the "hiccup" when will you fix that in the software? On a scale of 1 - 10 how hard is this to learn to tune and install this bad boy? Bob, rustang?

is the lean buck while driving or idling? (Or like 3 seconds after hitting a button) It can be at either time

every once in a while, while saving the settings to memory (3 seconds after you press a button) the unit has to clear a page of memory to save to. When this happens you will feel a hiccup. If the car is idling it may stall. This won't happen if you're not tuning.... (I'll fix this in a future software release) This makes complete sense now, because while trying to tune it would do it, so we tried to reproduce the hiccup so we could log it. Well whenever we did this, the car would drive with no problems at all, so we'd go to make an adjustment here or there and boom, lean hiccup again. Eventually we got a log of it, @ 40% throttle i was making 7psi and the car went straight from 12.1: 1 to 15.2: 1 and back down again. After this incident I called it a day as somethign like that could be quite catastrophic at WOT and a higher amount of boost. Now i see that i should make a run, log it, make a change and go make another run. No more tuning on the fly until you take care of that bug

FYI...This NEVER caused me to get any knock counts at all which is good

Did you load the tunerpro that was included with the unit? Yes v.4 i believe
Do you have any palm sync software running? It might have been running in the background i'm not sure (no palm was hooked up to the laptop though)
what brand of usb converter are you using? Its my neighbors that ive been using for the past year to tune my emanage. It doesn't have any brand name on it, the drivers indicate that its "USB v1.2 cable" so its probably some generic thing. i think im gonna get one for myself though, any brands you recommend? where did you get it from?

Colorado As far as tuning difficulty, id rate the MAFTpro 8/10, afc - 5/10, maft 3/10, Emanage 7/10, haltech (standalone) 9/10

the afc and maft are pretty easy because well the maft is just 4 nobs and the afc has everything right there.

the emanage is a little tougher because you have to get it to connect to your laptop, messing around with comm ports and stuff, then theres a lot more variability on what you can do. you can tune by boost vs rpm, tps vs rpm or airflow vs rpm and you can also change timing.

the maftpro is even tougher because it does a great deal of logging and tuning with the same software. Theres a little more of a learning curve than with the emanage but in the end your better off. And theres a lot of adjusting minor things like throttle tip in enrichment, auxillary rpm engagement (for my water/meth), then IMO things like a wideband are absolutely necessary with something like the MAFTpro.

the haltech is a standalone ecu, basically its like the AEM, you have tons of stuff to setup to get started, you have to run a strong ignition, wideband, map sensor and other stuff are all necessary. You tune on a 3d map of Boost vs RPM vs TPS, so its difficult when you're first starting off, but once you get the hang of it, it allows the ultimate in adjustability and accuracy (there is no tricking the stock ecu into thinking its getting a particular airflow value)

oh yea i almost forgot

my car is throwing the code 13

- INTAKE AIR TEMP SENSOR

it seems to be working fine, any idea why this code might be thrown?

The brown wire on the 10 pin connector feeds the IAT input to the ECU, recheck that connection and see what V Out1 setpoint is set to in the settings page, it should be about 2.5 volts, and the ECU should report about 77 degrees.

USB Converter.

I am using this one.

http://sewelldirect.com/usbtoserial.asp

anyway, if you had a previous generic installation of the tunerpro software, when you install over it, the old preferences are saved. Your old preferences were probably not correct and need to be setup.

Are you saying that there is no hardware being detected, or that the logging function cannot connect?
