Hey all. I am new to Honda-Tech and Hondas in general but I have turned a wrench or 2 in my day so I am not a complete noob. I have a del sol which has had a d15z1 swapped in to it (bought it this way). It has a p06 ecu in it right now (I know, I know) and I would like some advice as to what my best option is going to be as far as cheapest ecu that will run the car decent (read: with vtec)(btw i have a 4 wire o2 which i would like to keep if possible). Would a chipped p28 fit the bill or does anyone have a p07 l01 or p07 l02 they would sell me? Any other options out there?

 

Chip your P06 and have VTEC added. It will work just as good as a chipped P28 once it's been tuned.

 

Didn't even know that was an option. Glad I posted. Thanks for the advice. I will have to do some research on this. Anyone care to spoonfeed me a diy?

Does anyone have experience with this kit? Any good? It's nice that they have all the instructions as well.

 

Xenocron would be a good choice or so is Moates.net. That is where I used to get all of my chipping components when I first started. Now I buy from Digikey in bulk. It's cheaper, but for you only doing one ECU the kits are the way to go.

Make sure you verify the ECU main board version before you order the VTEC components. The board version number location is circled in red.



Your looking for the last 4 digits.
11F0,
1720 or
1980

 

googlers: https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/d15z1-o2-sensor-2783135/ was helpful too.

 

Thanks again for the advice. From my understanding doing the vtec conversion and chipping the p06 essentially turns it into a p28 and i can use a basemap for that ecu and my motor(eg the one in the above linked thread).

 

Correct Once you chip an OBD1 P06 ECU (add VTEC and/or IAB) you can run any basemap you want.

 

Have you though about just buying a used D15Z1 ECU ? I might have one
FYI.... if you do use a chipped ECU don't turn the rev limit past 7K. The valve train isn't strong enough to keep the pistons an valves from touching.

 

Thanks for the tip on the rev limit. I considered a p07 like I said above but I would prefer a cali spec one (l01, l02) which uses a 4 wire o2. I am pretty handy with a soldering iron so I am leaning towards using the p06 and adding vtec and a chip.
My p06 is 11f0 so it should be an easy job. I am concerned i might botch it and be without a car cause this is my dd but it looks easy enough.

 

Or buy my p06 already chipped and converted

 

Thanks for the offer but like I said it's all about doing it as cheap as possible. Unless of course you want to sell me your ecu for the $30 the kit costs

 

I'll check to see if my P07 is a Cali spec, I have a stock D15Z1 base map (bin) if you need it.

 

Well... I chipped my ecu and have been having trouble getting the chip to work. I am getting a solid cel which I believe means the car is in limp mode with an ecu error. I installed a switch on j1 so I can switch the ecu back to stock where it performs as it did before I chipped it (at least I didn't break it ). I re soldered any questionable connections but I believe my issue is with burning the eeprom. I have a willem programmer so I can't burn with crome. Anyone have any good resources on how to burn a good basemap onto a chip with a willem? Is there anything I should be doing to the basemap bin file before burning? The burns I have done have verified ok so I am fairly confident I am burning it right.

 

Answer:
Offset 8000 was the trick for me. Found it here: http://forum.pgmfi.org/viewtopic.php?t=8076

 

just double checking? which ECU you end up using? cause i have the same engine my self (D15Z1 vtec) and still looking for a ECU and ecu harness..

 

you should use a 92 95 civic vx ecu that is a vtec-e engine vtec engages at like 3k
