ok me and my friend was talking today about boosting on a stock obd2 ecu. he was telling me that i can do it as long as i dont go over 10psi. cause i have a 96 accord automatic YES am going boost it i got most info that i need. he was saying they had 7th gen and 8thgen civic and bmw doing boost on a stock obd2 ecu with no problem. so i wanna know if i turbo it with my stock ecu would the car drive. i know people dont tune odb2 ecu only the emange can tune it. PLEASE HELP ME OUT

 

well i wouldnt be boosting the auto......
thats a problem waiting to happen.

and everyone knows the f22 can hold way over 10 lbs stock.

i suggest just getting a jumper harness and putting a obd1 ecu in, easier to tune.

 

yea i was thinking of getting the stepdown harness and get a chipped manual obd1 euc and plug it rite up. instead of getting the greddy emanage

 

your going to run a manual ecu with the auto or swap to the 5 speed?

 

yea am going to run the manual ecu with a auto. its bin done this dude on cb7tuner got a chipped ecu form a h22 hatch. and he put it in his car. he is chirping 1st gear with out going thru the gear box. works fine with no problem

 

well the auto is not going to last long. just warning you. honda autos are not really the strong point of the company.

 

oh and what are you going to do about the TCU? you are OBD-2, so, your trans is OBD-2 and is auto, so it has a TCU.

 

This post makes me giggle.

No you can not run a turbo successfully with just an OBDII stock ECU.

You need at a minimum a piggy-back solution. The easier method however would be to downconvert to OBDI

 

just a giggle?

 

am going to use a tranny cooler and my tranny is rebuild

 

yea use the same tcu

 

well good luck and have fun with your excess torque steer.

 

are u saying this in a good are bad way about the torque

 

a bad way. the auto does not have intermediate shaft. it has unequal length driveshafts. the intermediate shaft was used on the 5 speed, and its purpose in any car is reduce torque steer, which will make you pull to one side. That allows the 5 speed 5th gens to have the drive axle lengths almost the same. whereas the auto has a really short right side (same length right side as the 5 speed) and a very long left side. They do have on the OEM axle for the auto left side a vibration dampener to help reduce vibrations because of how long it is, but you are going to have a pull to the right side when in high acceleration, like WOT, and considering your turbo idea, that could be very unsafe to be pulling to one side and a pain to have to control.

 

I'm glad I finally found my way back to HT.

I have a 97 Auto Accord, w/ OBD2 ECU and it's turbo. I have experiences most/all of what you all are saying

Dude, it may have been done but the TCU will be a pain in the butt and very expensive. I am pushing close to 10lbs now. I went with the emanage for the tuning option and its almost impossible to fight the OBD2's desire to keep the car stoich. Notice I said ALMOST impossible, I managed to do it but it relied on overwhelming the OBD2 to the point of turning itself off then scaling back to slightly rich almost immediately.

On to the tranny, the pressure makes it want to shift on its own sometime which can be a pain if you're just cruising and barely begin to spool up. I have a larger snail so 3k is my full spool, but once I get close the car tends to shift gears in preparation - I've gotten used to it but every damned mustang and domestic car thinks I want to race when it happens.

The axles are defintely the weak point in the whole scenario. I've snapped two of them already. The longer one to be precise and torque steer was an issue but you learn to overcome it at the track

If you've got more questions let me know cuz I've seen everything when it comes to turboing an auto accord, even melting alternators. Yea I know how in the hell can that happen right? It's happened...
