going down the socketed ECU route

geany · Post by **geany** » Sun Apr 08, 2012 1:13 pm

So decided to take the plunge and go down the socketed ecu route. I have the 99 red top 5th gen.

Now my question is if i buy a socketed p28 ecu from the likes of H-tune and then a copy chip off nucleustylzlude and get a ODB2 to ODB1 conversion harness will i be good? Obviously will need to get tuning set up. Thinking of talking to performance autoworks about that one as its only about an hour away from me. Hoping to get my larger TB installed and set up at same time.

Am i being naive in thinking this is all i need? Mods are 4-2-1 manifold greddy evo cat back with de-cat type s intake k+n filter. Just fancy a slightly lower vtec x over. no expecting big gains just a nicer set up ride with a few improvements

why dont you get a vafc? be a lot cheaper

Not really looked into them. Assume it's more than a vtec controller. Also felt a socketed ecu would give scope to move to Crome or Hondata if I wanted at a later date. Wouldn't have the foggiest on fitting one. But ecu and harness is all plugs and leads I think.

Don't know what you'll gain with a bigger TB from that setup but what you described above is basically the setup Rich tuned for me, minus the ATR intake, and he got 228bhp with a lower compression bottom end

. STK had the full ATR setup, only intake manifold and CAI different from yours, and got 237bhp. Rich did say the type S intake was a bit restrictive on mine up at the top end...

There is a hondata S300 socketed P28 ECU setup on my car, I think if you bought a spoon chip your need to install a resistor pack and change your injectors as the map is for peak and hold injectors not saturated ones.

I'd drop PAW an email, they'll send you on the right path

Mailed performance autoworks about it. TB I just have in my garage so thought I may as well use it. My red top is 11:0 compression I think not sure how that will affect it. Been toying with ATR intake just wasn't sure if it was a straight swap what was involved in swap. Would be interested to know

AFAIK the intake is not a straight swap, there's some drilling that needs to be done or something! I'm sure whoever comes in here next will be able to explain better

The 4G P13 ECU modded to fit a 5G does not work. Mills tried it already. As said either get a P28 or P72 with a tuning program that your tuner can use. If you choose P28 I would get it modded to allow for IAB control for the Preldue;)

I was looking at getting one from H-tune they offer the IAB service for a small extra charge. And a single wire vtec whatever that is. A couple of my mates are running ECUs they have socketed enhanced etc and have no issues.

From what I gather the chips are as the are right? Can't be tuned. Or is tuning tweaked some how. Obviously Crome Hondata etc is all customisable but at a much greater cost.

The only way to tune a 5G is to go either:

Piggyback like the Dastek Unichip
Full stand alone like the AEM
P28 or P72 with your choice of Crome, Hondata, Neptune etc...

All will need tuned once fitted to your car.
