Hey guys
I am in the procees of talking to EJ8_Man here on HT about purchasing an 99 JDM ITR ecu for my 97 gsr. Will any problem arise from this.
My engine has USDM p73 pistons, 4-1 headers, CAI, full 2.5 exhaust and soon to come cams and skunk 2 intake mani.
I tink the first problem will be my intake mani....since it has them buteflies.

Oh and what is the code that read on the jdm 99 itr ecu.?
Thanks guys

 

Yes that ECU will throw off a code for the secondary butterflies. Apart from that, you should be good. Just get a basemap on it, and tune.

 

?


did you even read his post? the p73 has no code for secondaries. you also can not basemap either ecu since they are both obd2a.

okay, now on to what you can do.

either buy the p73 and use ITR cams only or buy an obd1 conversion and ecu along with a hondata s100 and spend the cash on a real tune. remember, the p73 is made for a SPECIFIC engine combo, don't get away from that. a skunk manifold, ITR cams and 11:1 compression will work fine on the p73 since it will more or less be an ITR engine.

 

Im set on getting an p73 ecu .It is to expencive to get the chipped ecu and go trought all the tunning stuff.

 

no it won't throw a code. I used a JDM p73 on my 99 gsr and it worked fine with no codes. Only changes were less torque down low and higher vtec setting around 6000 RPMS.

Don't make comments if you have no idea what you are talking about.

 

make sure you stay set on OEM ITR cams in your build

 

Since i'd like to be able to tune the car i would go with what idrivesideways mentioned with going obd1 harness and hondata/or your choice of software. yes its a little more money but the tuning possibilities out weigh the cost down the road.

If your set on doing the itr route and don't plan on getting any thing other then oem itr/ctr cams get the jdm itr ecu.

 

I gave it a good tinking and i will get an obd1 gsr ecu that is already chipped with an jumper harnes and a map to properly run my engine all for 200$. Is this a good route. Or i have an option of getting an apexxi vafc for 100 brand new. I know that the apexi is just a piggy back and it messes with the ecu or how ever it work. Lead me in the right way guys.

 

a vafc still will require a wideband to tune the AF properly. if you do the obd1 conversion don't be an idiot and expect a basemap to be perfect. spend the money on a real tune. seriously though. if you just use ITR cams and the p73 it's not half bad. these engines are retarded to make power with at any rate. you have to spend a good amount of $$ to move past stock ITR numbers. tuning, cams, compression, high dollar headers. ported heads etc. even then it's often a few thousand that makes the difference between 175whp and 200whp. think out your end goal before you buy

 

Yea why would you do thats its only the right thing to do *rolls eyes* But basically you dont want to spend the money to do it the right way but your willing to spend money on a ecu thats really not going to give you any power gains.

 

Yeah,
After talking to a tunner here in Sac. I tink it was Midnight Performance. He said that its going to still run lean. Then hes like " I got an Apexi vafc for 100 brand new" and ill tune it for you for another 250ish". So i then talked to a guy that tunes my budies cars. Hes gonna hook me up with ecu and a jumper harnes and a map for 200. Then like u guys said. Ill get a street tune from him. Or shuld i get an acuall dynno tune. I tink its not worth to get a dynno tune just for the heck of adding more fuel so my car wont run lean and pay 250 for just that.

 

Youre not getting the point.
Im not going for the "b18c1" that can beat an "b18c5" deal. I just want an engine that will run good/great and spank some v8ts once in a while. Not an almmotor dyno queen lol. When i was rebuilding the motor. There was a good deal for some usdm itr pistons, new rings, and gsr roods with arp cap bolts and studs, what ever u call them, all for 200.

I know that the basemap isnt the best thing. But it will run my engine alot better then my stock ecu. LOL i didnt tink out my goal before i bough. What im doing rite now is. Save up buy a part, save up buy that. Then just put it all on there.

 

Glad to hear that, thats the right way, yea for what you got your not going to get much more outta a dyno tune so a street tune will be fine but glad to hear your doing that.

 

I still don't think you know what you're doing. VAFC is a bad choice.

 

the vafc will only help with AF not timing. buy a wideband and tune it yourself. it's not at all hard to do

 

Yeah after i read what the piggy backs do to engines etc etc.....screew it. save up another bill and get the chipped ecu and harnes and a street tune.

 

Iknow its a bad choice thats why i am not getting it and saving up to get a chipped ecu so it can be tunned down the raod when i get upgrades.

 

first of all you dont have a cai. you have some ebay crap short ram that basically does the same thing as a stock intake by sucking hot air from your engine bay and giving you really none extra horse power. It may sound good but thats about it. A cai sucks cold air from outside which is more dense and which expands more when ignited. yea so your wanabe "cai" is nothing

 

humn.....lol how long did that take you to google that.....lol
funni is that you were running this whole summer whith an short ram under the hoood suking hot air and giving no extra ponies. What happens when the car is moving. Theres fresh air going trought under the hood. Oh and that aem v2 carb lgal stiker doesnt give you 15 instant whp. Its just a pipe with an filter that happened to be lucki enought to get a carb stiker slapped on it and priced up to 300$. Ebay not ebay as long as it does what its suppose to do and make some kinda loud noice im happy. Oh and btw it came with the car so im not losing anything

 

for pete's sakes there are 3rd graders with better writing ability. the longer this goes the more it becomes obvious that you should be spending your money on education, not car parts ...geez

 

Ive lived in the USA for 9 years. Going to be 10years next june. And i personaly dont really care how i type as long as other folks understand what i am saying.
The previous post was typed up in an hurry.

 

no did not google it. its basic logic

I never said anything about my short ram in summer. your just saying you have a cold air when its short.

second, there is a big difference in air temp from in the motor bay and the outside I dont care how good it circulates

yes we know it does not give you 15hp but its better then short ram

 

hahahahaha good point

THUMBS UP

 

MODS Please lok this tread. I got a chiped P28 with an skunk 2 harness. no need for this treat no more.
Thanks

 

Who is street tuning your car?
