Hey guys


I was wondering If you could take an existing MAF TPI
and exchange it with a Speed density TPI with proper ECU
and harness??

SD TPI doesnt require a sensor in front of the throttle
body .. which goes good with my plans for the car.
and from what I hear .. performs well in altitude.


What about performance? which is easily susseptible
to modifcations?

Thanks for the advice

 

Its totally possible and if you are handy with a laptop, infinitely more tuneable than a maf car. I plan on doing this same swap in the near future. But I am taking everything off a 91-92 car and having it powder coated and what not before its all installed

Here's all you need to know: http://www.eecis.udel.edu/~davis/z28/ecm_swap_730/

I've done the swap myself on my '87 and it ain't that bad, you just need to triple check your work. You can do it!

 

You guys are waaayyy to generous with your
work and knowledge.

Thank the heavens :hail:


Where do you find the Eprom tuner program for the laptop?

and does a NEC 133mhz Pentium qualify?? :shrug:

 

I use a Gateway P166MMX. The MMX instructions shouldn't matter much for this task, and the 166 vs. 133 shouldn't matter a whole lot either. I've heard of people running this stuff on a 286. (well, the datalogging stuff). TunerPro works great on this laptop as well. I'm running Win98 SE with 128MB RAM and a 6gb hard drive.

 

Where can I get a hold of these programs? such as tunerpro???

? I don't know if I agree with that. I've worked on and tuned both. And I know a LOT of very fast MAF cars. Probably the most difficult thing to tune on a MAF car is the MAF Scalar tables...but that's only for part throttle and/or idle. In WOT, people tend to adjust the fuel by the PE tables...so the myth that your can't adjust the MAF system for high HP applications when you exceed 255 g/sec is, well, just that...a myth.

Yes, SD has a "cleaner" intake but it isn't the big restriction that people think. In fact, I still haven't seen anyone produce any quatitative data on a very high HP application to show that the MAF system is noticeably underperforming a SD setup. And then, the question would always be...was the tune 'optimal' on both setups.

After working and playing with both, about the best reason I have seen for converting to SD is, you need a new MAF or MAF ECM and it's cheaper to install a SD ECM. But if you have a perfectly good working MAF system, I would stick with it.

 

maf is easier to tune, don't believe the hype

 

Can you guys help me. I want a basic tune. Nothing fancy, but I feel with free(er) flowing exhaust and the few mods I have that the car could benefit from a tune. PLEASE HELP ME!!!! I am in dire need on info how to do it myself. Thanks

DIY PROM-board read the stickys, should be a good start...
