i had a 406 with ACCEL DFI system in it im just wondering if i can use that
DFI ECM on L98 350 with few mods...i tried to plug it in the way it is, but the car wouldnt even start(didnt think it would but thought i should give it a try) so im not sure if i can reprogram it to l98 specif. since laptop could be used...thnx

 

Yes you can use the DFI. Is it a Gen 6?

To get the car started you should go into the base fuel map and pull 10-12% fuel out across the board. Timing should not have much of an affect.

 

yep its gen 6... i just cant seem to find a wireharness for it :/ and dl the software already...now is it going to better than burning a PROM chip or it doesnt relly make any difference besides that DFI could be tuned easier (through laptop)...

 

I assume you're talking about the harness from the laptop to the DFI?

Also, some may disagree but I like the tuneability of the DFI. I have a 406 in my TA with 11.0-1 compression and a solid roller cam that I pass emissions tests with. The only way I can accomplish this is through the quick and easy programming of the DFI.

I also use a stand alone wideband for accurate A/F ratios.

 

yeah thats the harness im missing :/ now im trying to see if anyone has it for sale it seems like not much left out there since DFI gen 7 came out...unless that harness fits too (i doubt it)...i think thats the best thing about DFI is that you can change anything at anytime yourself even while you driving

 

try fast track performance, they have the 5ft and 25 ft cable...any accel dealer can get it you just have to call

 

It's like this, I can make more power quicker on the dyno with the dfi vs. the 7730 anyday. You can work the adjustments so fast that you can really surpass the stock ecu anyday. They do have something with the the stock computers now where you can make adjustments on the go I believe.

 

i just realized that i might haveto rewire the whole car to have the DFI ecm installed...because the only thing i have from DFI is the ecm itself...asi understand it comes with its own wire harness incl injector wiring...i thought the only thing i need is the cable that hooks up to the laptop but apparently not unless im wrong

 

My dfi just has a harness to be a plug in play deal into your ecm location. No engine harness needed just your orignal harness.

 

You don't need to replace the harness. You can use and adapter harness from White Racing http://www.whiteracing.com/complete.html or HorsePowerConnection.com (I guess they bought up Fast Track Performance) http://www.fasttrackperformance.com/ECUHarnesses.htm . I've always used the White Racing adapter harness myself. Either should also be able to help you with the Interface harness for the laptop.
