MPI Tuner Anyone?

[MPNick]

I thought this was known from a long time ago.

What about venting the blow off valve to atmosphere? That falls under the same category.

I know that I have talked about it before. That does not mean that changes have been done to cars. It seems like anytime you make a post on what is right or wrong peole always talk about how they have it working the wrong way without any problems. I am sick of debates over things. I know what we have for out by testing things. I then post what we found out. BOV suck with the stock MAF. Some people use them and claim they have no problems at all ever. We have the right meter to use with a BOV. Two forum members have them and will installing them on their cars.

Thanks again

Cool. I had thought the the breather tube was a done issue back when FP was active on the board.

And the blow off has been debated for quite sometime, but no one liked it. However, I thought it fell under the same principle as the breather tube.

It is more then just a breather tube. Under boost it will draw from the low pressure zone that is in front of the turbo. This will greatly reduce the crankcase pressure that your engine see's under boost.

you are slow...(outie)

yeah well...im the one that lost the engine...this is so frustrating...

Anyway, I think im going to unplug the MPI from the injectors and make it only run the extra injectors and pull the timing....what you think?

Where are you at with this? Are you still tuning the stock injectors?

Not at all...I have tuned the injectors for initial boost, then the aditional injectors come in....its a very smooth transition.

How is the idle and start up? What about the fuel cut? You and Dana were the last two who had problems getting the stock injectors to tune right. Glad to see you have got things working fine and did not give up and just tune the extra injectors.


Thanks again

Idle, Cold Idle, Cold Start, Hot Start is just perfect. I mean, I can make it the way I want....

Fuel Cut? I dont know, Im just boosting 5psi, my clutch cannot handle more boost because it slips over 4psi, it sucks, stock clutch could handle 8psi in the past, I think It got oiled when the engine broke. I definitely need a new one.

1)I know the MPI can data log, but what kind of data can it datalog?

2) Can the MPI tuner accept at 0-5v input? Like if I were to add a wideband with a 0-5v output could the MPI accept it, and be able to datalog the wideband data as well?

We do read 0-5 volts on three scales. You may be able to install your WB on one of them.

If Perfect Power can tell you how, I can give it a shot next, after I finish the ultimate O2 clamp setup!

I noticed in your sig that you have the PLX 300 wideband. I was thinking of going with this wideband with the MPI turner, but I wanted to see if the MPI can data log the aftermarket wideband data.

Do you plan on installing your PLX 300 wideband soon? I'm interested to see if you can get it to talk to the MPI turner.

I don't have it hooked up to the MPI. If you want to datalog the WBO2, get the M-500 one that is wireless. If Nick comes up with it, I'll test it out.

The MPI would only give you a voltage reading on the WB.

Do not to long. The MPI is only on sale until the end of this year.

Did I read this right, is the MPI being discontinued? Are you bringing something else out better?

thanks

Here we go, more then a few people have told me that I need to give more info about the inner working of the MPI Tuner. I can only go into some of this but not all of it. Sorry but this is how the world works. I will not debate anyone about anything. I will agree to disagree with you and leave it at that. If you ask me a question I will tell you if it is being done with a customers car already.

Here is a list of what we can do. Keep in mind that on some controls you can only do one and not all of them. Ask me and I will tell you what you can and cannot do at the same time.

Total fuel curve tuning
O 2 fuel tuning
Total timing control, add and retard timing plus boost or NOS retard
extra injector control
NOS control
Boost control
VTCS control
extra inline pump control
duel mapping, flip a switch and go from map A to Map B
Data logging, with this we can help tune your car over the internet for you, at no charge.

no charge software updates

Thats about it.

Thanks again

Later.....Nick

just a short note to say a big thanks to Bigg Tim and supa saiyan pr5!!!

Tim really know his MPI tuner. (yes) he was on the phone with me & jeremy for 90 mins tuning the car! thanks man! i feel a lot more comfortable and understand the tuner much better. i need to make a few more adjustments to get my a/f ratio down a bit during boost, but the progress we made the other night was excellent!

RIGHT ON!!!! So any luck with your search, did you find anything? I spoke to Nick about it and he agreed that there has to be something worng with your car. For you to make changes to the fuel calibration and the car not react at idle, something is not right. It may be something minor and easily overlooked, but still something. Good luck, give me a call when you are ready again.
