I would've posted this over at Hyundai Performance but their sight is so jacked up i can't figure out to post a new topic.

I was just wondering since the new 2003 Tib is going to have a "revised version of last year's five speed" how much better is it going to be versus the old 5spd? How is going to be better? Is it even going to be better or just revised?

Is it going to have 16"s standard with 17" on the GT? Would they fit current models?

Sorry just really bored here at work.

Since i can get all genuine Hyundai parts for cheap I was trying to convert as much as possible with other Hyundai parts. smile.gif

 

The revised beta in the new Tiburon will be the same motor that is now in 2001-2002 elantras. MAP sensor rather than MAF and shim over bucket valve adjustments rather than HLA's.

 

The site is jacked up? How so?

The 5-speed will be slightly improved. The shifter will definitely be getting a new design.

As for the rims, the base model will come with 16" rims, while the GT will come with 17" rims, and no, they won't fit the current Tib as the 2003 Tiburon is 5-lug.

 

Random,

I thought US vehicles had to have a MAF rather than a MAP? Isn't this the reason we were unable to do a simple Superchip to date? Or was the MAP/MAF thing just Hyundai decision and not Federal reg?

 

From what I have learned MAF was easier to do ObdII with hence why they sent them to North America that way at first, not any regulations on sensor type. As for the super chip there are a few out there but the results have not been that great with some, that and the differences between the ECU in the model years, and surface mount ship makes it difficult to swap, you need an entire reprogramed ecu. Unichip/superchip in the UK has the ICON that appears to work but no one has written the MAFS version of the software for us the last time I checked. I think Zorro has one.

 

Anyone wanna step through what all is needed to convert a MAFS Beta to a MAP Beta?

 

It is not that hard...just replace ECU for one made to work with OBD-II and MAP sensor, Replace the stock intake manifold with one that has the map sensor built into it, splice some wiring harnesses and your done.

However...a stock MAP sensor is not going to be an upgrade. A stock MAP sensor is not going to like boost. A MAF will deal with boost much better than a stock MAP.

 

Are there MAP's that can be used that don't require an IM swap?

MAFS handles boost better, but all the high-end management kits aren't MAFS compatible (Haltech). rolleyes.gif

 

There is no reason to do a MAF/MAP conversion. Stock MAP sensors do not like boost on N/A Engines. Just ask the Honda crowd about how their MAP sesors trigger an error anytime they see postive pressure rather than vacuum.

If you are going to go Haltec, you do not need to do a MAP/MAF conversion with a stock ECU as the HalTec will replace the ECU and the Haltec has their own MAP sensor that you should use.

There is not gain/benefit or reason to do a MAF/MAP conversion using stock parts.

The MAP is built into the Intake manifold. There is probably a way to remove it, but I do not think our Intake manifolds have the provistion to mount/place the MAP.

Ahh, the answer I was seeking. Thankyouverymuch!
