After having a brief conversation with someone on this board about a harness for my V-AFc they suggested I instead go with a Skunk2 ECU. What do you guys think? I have heard the Skunk2 ECU definately smoothes out the power band on a Type-R making some decent power; but what about someone like myself who is planning on modding only slightly (JDM 4-1 Jethot header, Testpipe, Icebox intake); does the Skunk2 ECU makes sense instead of a V-AFC here?

Note: I tried doing a search, nothing very helpful came up, although i know this was discussed at one point.

 

I'd actually reccomend both. The Skunk2 ECU has some VERY nice timing curves, but runs increibly rich. The gas mileage is horrible. You can use the V-AFC to lean the mixture out. thus increasing gas mileage and also giving you a little more power.

 

In fact you need both. The skunk2 program just dumps a lot of fuel (too much) all the time. Youll be running rich at idle, part throttle, full throttle.

The reason why so many people say the skunk2 program works is becasue they are lean from all the air mods (intake, header, cams) that they think the ecu gave them a lot of power. (In fact, the thing that gave them the power was just the added fuel). Which could of been done with the stock ecu and just bigger fuel injectors or a fuel regulator.

It is cheaper to get the injectors/regulator than buying an Obd1 ecu, harness converter, Reprogram fees, and a fuel controller.

 

I would say get the Skunk2 ECU and an adjustable FPR. If you have the extra cash for a VAFC get that too.

Just by decreasing my fuel pressure with the Skunk2 ECU I gained a few Hp up top.

In most cases the Skunk2 ECU runs a little lean in the midrange and nice and rich up top. That is what I have found on the dyno with a wideband O2 sensor.

If you need a Skunk2 ECU I have an extra one laying around. Email me at kenji211@gte.net

You can actually get your stock ECU reprogrammed if it is a 97-98 ITR. They can be reprogrammed to run perfectly with your settings and giving a fair power gain. You don't need the conversion harness and you can also replace the reprogrammed chip with the stock one any time you want to go back. Try looking on my website or email me.

 

skunk does not reprogram OBD2 ecus.
