Is my ITR worth tuning?
 

01 DC2R

Mods are: Titanium exhaust manifold (not sure of the brand but was told Mugen replica), with a 2.5" Fujitsubu Power Getter cat back exhaust and a Comptech ice box.

Now, with these simple mods, is it worth tuning? I ask because the VTEC comes on SO strong, it physically puts me in the back of my seat, so i was thinking maybe a good tune will be able to even the powerband out a little and perhaps lower the VTEC threshold. Yay or nay?

After tuning my GSR (I/H/E, Skunk 2 IM, 65mm TB) the VTEC engagement is at 3800rpm, and provides a lovely amount of torque in the mid-range and very smooth power delivery, where with my ITR its nothing then BAM at 5700rpm. I understand ITR cams are a lot bigger which may contribute, but any chance of getting similar VTEC crossover results of my GSR with a tune to my ITR?

One last thing aswell, what is this i hear about each ITR ECU is programmed specifically to the keys and immoboliser system, does this mean if i buy an obd1a ECU with the obd2a conversion harness to tune it with, the car will not start? Do i need to take it to Honda and get it re coded or something similar?

Not interested in VTEC controllers or anything else like that either.

Thanks

Proper tuning will generally yield a better powerband and overall power when you are comparing a stock ecu to a tuned ecu when you have intake/header/exhaust.

Using an obd2b to obd1 ecu jumper harness & chipped obd1 vtec ecu or hondata s300 system would be the ideal solution.

Thanks for that. I was just going to buy another P73 ECU, socket that and chip it and use that to tune, but after reading that link, why cant the p73's be chipped?

Re: Is my ITR worth tuning?
 

Obd2 ecus are not supported by tuning software on the market.
You must use an obd2 to obd1 ecu jumper and obd1 ecu setup.

Ok thats that part cleared up, also one more thing..

What is this i hear about if i buy another ECU, i would need to take it to Honda to get it re coded to my keys and immobiliser system?

Re: Is my ITR worth tuning?
 

No, using an obd1 ecu eliminates the immobilizer.

Thanks for your info, will post up some results once my tuner gets off his lazy butt.

listen to mtber
he knows he's shit when it comes to tuning.i feel he's one of the best tuners around.

Re: Is my ITR worth tuning?
 

Yea i dont doubt that...

Another thing, is there anything that needs to be done under the dash for the immobolizer transponder?

Re: Is my ITR worth tuning?
 

Nothing needs to be done to run an obd1 ecu. Simply plug & play the adapter harness and obd1 ecu setup.

[QUOTE=zccr-xsi;45834235]No, obd2 distributor will work with obd1 ecu, no modifications needed.
